Abstract
A system for detecting and preventing power theft on a branch distributor conduit (9) between a transformer/distribution circuit (13) and an electricity meter (M) at a registered customer (1 ) of a power distribution company is provided. The system comprises first sensors (4A) and a first converter unit (5A) located within a sealed box (2) of an electricity meter (M) at the customer (1 ) for determining a first current value representing the current in the power feeding cables (7) and second sensors (4B) and a second converter (5B) located within a connection box (3B) measuring a second current value representing the current in the branch distributor conduit (9). The connection box (3B) comprises further a first electronic unit (10A) which determines the difference between the said first current value and the said second current value. If the difference is above a threshold value power theft is determined and a signal is transmitted from the first electronic unit (10A) to a server (11 ) located in the power distribution company for registering power theft, determining the location of the registered customer (1 ) and/or branch distributor conduit (9) and for switching off the branch on which power theft is determined by means of a switch (8A).

The present invention refers to intelligent differential self-surveilled schemes to track or prevent power theft by the so-called "hooking" in power-supplied areas, and offers the possibility for a remote reading of power consumed in (1) Registered Customers of a Power Distribution Concessionaire.

> (12) Communication means between (1OA) and (lOB) EDEEs- Intelligent Differential Electronic Equipment and the (11) Company's Server.
Energy theft (also known as hooking) is made by totally or partially stealing power directly from the (7) Power Feeding Cable of the Registered Customer positioned before the (M) Energy Meter, as well as by tempering with (M) Energy Meters or by directly hooking to the (9) Branch Distributor.
Some customers, generally in poverty-stricken places, are not registered as consumers of the local Power Distribution Company, and power theft through hooking is mostly easily identifiable and unskillfuUy made in the (9) Branch Distributor or in the (13) Transformer or Distribution Circuit, giving rise to a chaotic dense tangle of wires as shown attached (Annex ID).
Power theft originating in the (1) Registered Customer is more elaborate, usually unidentifiable, etched into the masonry, likely to be handled unobtrusively and placed before the energy meter, tempering with the latter. This kind of installation also allows for a parallel deviation, namely before the energy meter or the general circuit breaker, feeding part of the power, there being theft of the power consumed at that moment. Therefore, the energy meter reads only part of the electrical energy, so the consumer will not be at risk of being caught when the power company employee comes in to check the meter. More sophisticated "hooking" utilizes elaborate controls to automatically switch off in the case the power company employee switches off the (7) Power Feeding Cables of the Registered Customer at any given point.
In an attempt to deter power theft, some power distribution companies have decided to make energy meters as visible as possible, and some companies even place them as close as possible to the (9) Branch Distributor. The latter practice has been facing antagonism on the part of consumers as they are unable to have access to reading the energy meter, a practice the Electric Sector enforces.
The present Application for Patent (AP) tracks or prevents the above described "hookings" at the registered no matter if they are unsophisticated or skillfully made.
This AP also proposes that the readings produced by local digital energy meters be readable and processed remotely at the Power Company's Control Centers, so local readings may only be resorted to in the case doubts arise, therefore interrupting a long-standing policy on the part of the Power Sector, but also making power invoicing processing less costly.
The "System" is dubbed self-surveilled because if any of its circuits are tempered with, the lack of reception of any entry data will make remote alarms go off, pointing toward the occurrence of an abnormality or describing this same abnormality depending on how sophisticated the process applied is. Alarms will also go off in the case the door of the (2) Sealed Box of the Energy Meter is open or if there is an attempt to temper with the magnetic field around the energy meter, in the case of electro-dynamic energy meters.
Although the "System" detects all forms of power theft, the integrity of the (2) Sealed Box of the Energy Meter should be given priority.
The principle backing the "SYSTEM" is that it is DIFFERENTIAL for any given anti- theft scheme, i.e., the potency that leaves the (9) Branch Distributor, disconsidering marginal losses, must be equal to the potency that passes through the Energy Meter (M).
Therefore, in order to oversee a (1) Registered Customer, the "System" checks the current that leaves the (9) Branch Distributor toward the (1) Registered Customer is the same that flows into the (7) Power Feeding Cable of the Registered Customer, which must be the same as the current that leaves the Energy Meter (M) of the (1) Registered
Customer. This holds true except for a small value adopted as a safety threshold due to the losses in the circuit, transformation ratio, energization current, etc...
What has been devised to avoid power theft in this kind of customer is to have every power feeding line coming from the (9) Branch Distributor to the (1) Registered Customer through the (7) Power Feeding Cable of the Registered Customer with these two connection boxes, as described below.
One (3A) Meter Reader of the Output Side of the Connection Box containing the (4A) Current Mono-phase Sources etched into the (2) Sealed Box of the Energy Meter (M), which will send the output data from the (M) Energy Meter to the (5A) Digitalized and Communication Circuits which, in turn, will send the resulting current signals flowing through the (M) Energy Meter to the (10A) IDEE - Intelligent Differential Electronic Equipment localized in the (3B) Connection Box of the Power Feeding Cable connected to the (9) Branch Distributor . The resulting current data may be sent through the (6A) Control Cables, Infrared, Optical Fiber, Radio Frequency or any other new technology such as Bluetooth, working under a communication protocol.
The resulting data of mono-, bi- or tri-phase currents produced by (5A) and (5B) Digitalized and Communication Circuits must equal the sum of a certain number of amplitudes at a given time interval and must be compared.
From four to eight control cables or from three to five data cables come from the (3A) Meter Reader of the Output Side of the Connection Box to the (3B) Connection Box of the Power Feeding Cable, depending on the data release model adopted between these boxes, and on whether the power feeding scheme of the (2) Registered Customer is mono- , bi- or tri-phase. Two pairs will be used for the door and magnetic field surveillance relays, localized in the (9) Sealed Box of the Energy Meter, if that is the case. Digital energy meters do not need relays to detect magnetic field variation. If the data between these connection boxes is wireless, the (3A) Meter Reader of the Output Side of the Connection Box should also contain a board bearing the function CLP associated to a transmitter. It is preferable that the transmission between these boxes be made by cable as the distances are relatively marginal and constant.
Another box, the (3B) Connection Box of the Power Feeding Cable that links the (9) Branch Distributor to the (7) Power Feeding Cable of the Registered Customer may have, optionally, a (8A) Contactor between the phases of these cables. If this is the case, it may have local or remote re-switching, depending on the philosophy adopted by the Power Distribution Company.
Initially, we will examine the status of one (1) Registered Customer, and, should power theft be traced, legal action may be taken on the part of the Power Distribution Company.
The Connection Box (3B) shall also have the (5B) Digitalized and Communication Circuits, which will transmit the signs resulting from the current demanded by the (7) Power Feeding Cable of the Registered Customer to the (10A) IDEE - Intelligent Differential Electronic Equipment localized in the (3B) Connection Box of the Power Feeding Cable to the (9) Branch Distributor . In the (10A) IDEE - (Intelligent Differential Electronic Equipment) an IDC (Intelligent Differential Circuit) compares the data of the current that flows from the (4A) (4B) Mono-phase Current Sources to a
reading above a given security threshold, where a mismatch points toward power theft. In this case, therefore, there will be a GPS (Global Positioning System) signal output or a Transmitter/Receptor of any communication means commonly used such as Radio Frequency, Cellular Telephony, Fixed Telephony, Satellite, Cable, Infrared or Optical Fiber which will transmit and/or receive a signal concerning the customer, therefore tracking it.
If the IDEE does not utilize GPS, the (1) Registered Customer must be previously geo- codified by a GPS in order to be registered in a Reverse Geo-coding program installed in the (11) Server localized at the Power Company's Distribution Control Center, allowing the Company to decide toward action-taking according to its own policy. This former method should be given preference. Because they are fixed customers, a mobile GPS is only necessary when the customer is first registered, which makes the "SYSTEM" more affordable as a whole.
The (10A) BDEE (Intelligent Differential Electronic Equipment) may be able to detect the occurrence of power theft and proceed to the automatic switch-off or restart of the power supply as much as to receive remote commands to switch off or restart the power supply of the (1) Registered Customer, and should it be the Power Company's choice, the (3B) Connection Box may have the (10A) Contactor.
The situations giving rise to power theft are reported to the Power Company's Control Center, informing the address of the customer where the power theft has been traced, thus triggering several (MMI) man-machine-interactions. For instance, power theft may be reckoned as an occurrence backing future action-taking, such as checking on the customer to collect data on a legal basis so the Power Supply Company can prove revenue loss, or activating a remote signal toward the connection key, switching off the power that is being stolen. Decisions guiding the "System" project are to conform to the Company's entrepreneurial policy.
From the (10A) IDEE (Intelligent Differential Electronic Equipment) of each (1) Registered Customer, the data resulting from the input current in the (9) Power Feeding Cable of the Registered Customer that feeds the control of the (9) Branch Distributor at the (11) Server will be sent to the (11) Server by those communication means commonly used Conversely, this same data produced on the current will be sent through the (6B) Control Cable or Another Communication Means to the (10B) IDEE - (Intelligent Differential Electronic Equipment in the (3C) Connection Box of the Delivery Point to the (11) Transformer or Distribution Circuit. In this case, control will be performed at the (10B) IDEE and the result will only be sent in the case of power theft. This solution is probably not the best one due to the large number of (1) Registered Customers along the lengthy range of delivery points.
Finally, for those customers that are not yet registered, whose hooking gives rise to the chaotic dense tangle of wires as shown attached (Annex IB-), the solution proposed by the "System" is to check on each (9) Branch Distributor separately so that the difference between the total sum of the potencies required by the several (7) Power Feeding Cables of the Registered Customers of a given (9) Branch Distributor toward the (13) Transformer or Distribution Circuit equals zero, unless a mismatch occurs. Therefore, when a hooking attempt along the (9) Branch Distributor is made, the potency required at this (9) Branch Distributor will be different from the potencies that are required by the several (1) Registered Customers. The control over the (9) Branch Distributor will be
made preferably in the control software of the (11) Power Supply Company's Server associated to the Reverse Geo-coding software. Each (9) Branch Distributor connected to the (13) Transformer or Distribution Circuit, previously geo-codified, constitutes a control group that contains the data produced on all the (1) Registered Customers that belong to a given (9) Branch Distributor.
The information on the potency that is required from the (11) Transformer or Distribution Circuit is produced in the (3C) Connection Box of the (9) Distribution Cable and sent to the Transformer or Distribution Circuit (11). This (3C) Connection Box has the (4C) Sources of Current, the (SC) Digitalized and Communication Circuits and the (10B) IDEE - Intelligent Differential Electronic Equipment, which may not have GPS and IDC functions, working via radio in the case the Scheme should use Reverse Coding and the control of the (9) Branch Distributor should be made at the Power Company's Distribution Control Center, respectively. The (10B) IDEE - Intelligent Differential Electronic Equipment may be able to detect both the occurrence of power theft and to switch off or restart power supply automatically as well as to be remotely controlled to switch off or restart power supply at the (9) Branch Distributor, should the Power Company choose a scheme with the (8B) Contactor and the IDC functions in the (10B) IDEE - Intelligent Differential Electronic Equipment. Data (12) Transmission/Reception between the IDEE and the Company's Server (11) may be made the same way as the former one, i.e., through any communication means commonly used.
The comparison between the apparent potencies in the Power Circuit (7) output, in the (9) Branch Distributor and in the Energy Meter (M) input is attained by comparing the differences between the current image obtained by the sources of current (TC). Such secondary currents are between 4 to 20 mA.
The (5A, B and C) Digitalized and Communication Circuits as well as the (10A) and (10B) IDEE — Intelligent Differential Electronic Equipment are fed by sources of 100mA of 12V, and communication between these equipment is conducted via a no-parity asynchronous communication protocol of 9600 bits/s and 1-stop bit.
Should it be necessary to receive the data on the electric active energy of each (1) Registered Customer at the Operation and Distribution Center, the computed information should be done ideally with digital meters extending to the (3B) Connection Box of the Power Feeding Cable through cables such as USB, RS485 or RS232, and then sent to the Company through any of the communication means previously mentioned. Unlike telephony, the Power Industry does not commonly proceed to measuring the consumption of electricity remotely. Initially, though, it is perfectly feasible to proceed to a remote measuring, and to resort to a local measuring only when doubts about invoicing arise, which is a cost-saving approach. In a second instance, both measuring the consumption and proceeding to meter reading may be done remotely.
The "SYSTEM" allows for several processes, depending on how convenient it might be or not to use (10A) and (10B) Contactors in accordance with the scheme used by the Company, and the legal conduct and entrepreneurial policy adopted by the Company. Among the several arrangements and processes that may be chosen from, the following must be mentioned:
a) Only remote assessment and simultaneous tracking of the (1) Registered Customer and/or, in the case of a non-registered customer, of the (9) Branch Distributor where power theft is occurring. b) Automatic switch-off and restart of power supply, when hooking is done and undone, respectively, at the (1) Registered Customer and/or, in the case of non- registered customers, at the (9) Branch Distributor, and through remote assessment and simultaneous tracking of where the power theft attempt is being made. Locally, there may be a visual or sound signalization pointing toward an abnormality so that the power theft agent at a given (9) Branch Distributor feels constrained and deterred from going on with the power theft. If power theft occurs at a (1) Registered Customer, the former should be notified that the theft has been traced. In the case of a hooking attempt on the part of a non-registered customer, the consumers) deemed a (1) Registered Customer should be communicated that power outage occurs due to power theft attempts in his/her/their neighborhood. c) Remote assessment of the (1) Registered Customer and of the (9) Branch Distributor, as well as simultaneous tracking of where power theft is occurring, and remote control to switch off and restart power supply providing hooking is eliminated. Visual signs and/or sound alarms should be made available in the sites where abnormalities are detected. d) Other combinations of systems may be used by the Power Company, according to its own convenience, in order to switch off or restart automatically or remotely one of the power feeding alternatives above mentioned, giving rise to other men- machine-interactions and legal action as the Company deems necessary.

Claims
- Claims -
This is a Claims for Registration of Patent of (ANTI-THEFT DEVICE) - "INTELLIGENT DIFFERENTIAL SELFS€RVEILLANCE POWER ANTI- THEFT SYSTEM (processes, components and schemes) MONITORED BY GPS
OR REVERSE GEOCODING", which consists of an intelligent differential self- surveillance system to track or prevent power theft, offering the possibility for remote reading of the (1) Registered Customers of a Power Distribution Concessionairy.
Energy theft (also known as hooking) is made by totally or partially stealing power directly from (7) Power Feeding Cables of the Registered Customer localized before the (M) Energy Meter, as well as by tempering with (M) Energy Meters, or by directly hooking to the (9) Branch Distributor, which may be blatantly identifiable as these connections are unskillfully made to the (9) Branch Distributor, which gives rise to the chaotic dense tangle of wires as shown attached (Annex IH).
The "SYSTEM" in this Claims consists of differentiated schemes that track and compare on an ongoing basis, through current images, the apparent potencies that run through the (M) Energy Meters of each (1) Registered Customer and the apparent potencies solicited from the (9) Branch Distributor. Likewise, they track and compare the sum of the apparent potency being demanded by the several (1) Registered Customers and the apparent potency being demanded by the correspondent (13) Transformer or Distribution Circuit. Should this comparison show a mismatch between the current and the assumed safety threshold, the "SYSTEM" acknowledges this as power theft and through the communication means listed in the report, transmits a signal to one (11) Server located in the Company. Depending upon the scheme selected, the "SYSTEM" will either register the power theft or will prevent the occurrence altogether by furnishing the exact localization of the customer or the Branch Distributor.
The "SYSTEM" also tracks, on an ongoing basis, the gate-keeping status of the (2) Sealed Meter Box and that of the permanence of the magnetic field reading that is restricted to the meter, in the case of electro-dynamic readers.
The above mentioned assessment of the apparent potencies are made by means of the images of the corresponding currents which in (5A, 5B and 5C) Digitalized and Communication Circuits are modified to resulting-currents, constituted by the total sum of a certain number of amplitudes of the images of current considered at a certain time interval, which are then sent to the corresponding (1OA and 10B) TDEE - Intelligent Differential Electronic Equipment, according to a no-parity, asynchronous communication protocol of 9600 bits/s.
In order to track the (1) Registered Customers, the (7) Power Feeding Cables of the Registered Customers., and the (9) Branch Distributor, the reading furnished by the images of current is provided by (4A, 4B and 4C) Sources of Current and are received by (5A, 5B and 5C) Digitalized and Communication Circuits, which in their turn are sent to (1OA and 10B) IDEE - Intelligent Differential Electronic Equipment. In the (1OA and 10B) IDEE - Intelligent Differential Electronic Equipment an IDC function (Intelligent Differential Circuit) compares the readings of the current against a given safety threshold, and should a mismatch occur, the system interprets it as power theft. In this case, there will be a signal output either for a GPS function (Global Positioning System) or for a Transmitter/Receptor of any communication means commonly utilized such as Radio Frequency, Cellular Telephony, Fixed Telephony, Satellite, Cable, Infrared or Optical Fiber that will transmit/receive a signal inherent to the customer, thus tracing it.
Depending on the scheme adopted, the IDEE may not have GPS and/or IDC function. If GPS is not available, the (3B) Connection Boxes of the Power Feeding Cable of each (1) Registered Customer of a given (9) Branch Distributor, and the (3C) Connection Box of the Power Distribution Cable to the (13) Transformer or Distribution Circuit will need to be geo-referenced only at the installation point, or when connection boxes are checked. The registered customers and its (9) Branch Distributor will be tracked by REVERSE GEOCODING.
In there being no IDC function, information on current is sent to the (11) Server to be analyzed differentially. Supervision of the (9) Branch Distributor will be done in the program, associating to the number of customers of this delivery point the power it demands, and comparing this demanded power to that demanded by the several (1) Registered Customers of this same (9)Branch Distributor.
With the data and information collected, and if it is its policy, the Company may switch off remotely energy supply to the (1) Registered Customer or to the (9) Branch Distributor depending on whether or not hooking is being made at the registered customer, or proceed to any other measure that proves revenue loss. Depending on the scheme adopted, the "SYSTEM" allows for automatic switch-off/on, when hooMng is done/undone at the (1) Registered Customer, and/or should it be done at a customer that is not registered at the (9) Branch Distributor. Such automatic action-taking are assessed remotely along with simultaneous tracking of where energy theft is being attempted. Locally, there may be a visual or sound signalization pointing toward an abnormality so that the power theft agent at a given (9) Branch Distributor or (1) Registered Customer feels constrained and deterred from going on with the power theft. Other action-taking may be adopted and are described in the Report on the Claims for.
The "System" is dubbed self-surveilled because it may trace remotely attempts to temper with the (2) Sealed Box of the Energy Meter as well as external changes in the magnetic field of the energy meter, when applicable. Moreover, any harm caused to the
circuits will trigger an entry data error at the IDEE (Intelligent Differential Electronic Equipment), thus maiding a remote alarm that detects problems in the "SYSTEM" go off.
