Introduction
Nowadays, various technologies growing rapidly and not exception for the technologies that used in the energy meter where it is always upgraded over time. However, the trick/method that used to stealing the electricity is also upgraded together with the newest technology that used in the energy meter. Knowing the trick that usually used to stealing the electricity is the important part to known to provide a simple and effective way to detect an electrical power theft. This week, several methods of the electricity stealing trick will be discussed together with the principle that will be used in the Electricity Theft Detection Metering System.
Objective
- To gathering the information of electricity stealing trick in real time.
- To provide a simple and effective way to detect an electrical power theft without any human interface.
From the researching that were performed, four common methods that usually used was found and it is as listed below:-
- Stealing electricity by under voltage technology.
- Stealing electricity by undercurrent technology.
- Stealing electricity by phase-shifted technology.
- Stealing electricity by difference expansion (DE) technology.
Below is the illustrations of the tampering methods of energy meter:-

However, this problem actually has been solved by upgraded the energy meter such as that has been discussed in the previous section but some of the new problem come out from that solution which is one of that problem is it will give health risks and proliferation of electromagnetic fields posed by RF-EMR.
Project Description
One of the solution which is by using existing energy meter called Electronic Energy Meter (EEM) but the concept to distribute electricity from the distribution pole to the consumer energy meter will be modified by adding another one energy meter on the pole side. It consists of Wireless data receiver, Micro-controller and GSM module to allow both energy meter communicate each other for the purpose to compare the amount of energy at sending and receiving part is similar or not. When the meter is tampered, the value at sending and receiving part will become different and not synchronize. At the certain point, Micro-controller will give the signal to the GSM module and it will directly to the utility company personnel. The system also will cut-off the supply that through along to the problem line and restart with the stored value. The figure below show the conceptual diagram.

Project Outcome
As the project outcomes, the principal of Electricity Theft Detection Metering System will be developed/designed as the conceptual diagram above. From this concept hopefully it can solve the problem that occurs especially in term of health risks and the major problem in the electricity arena.
ok, good exploration! my question, what is the difference between the smart energy meter with your proposed EEM that embedded together with wireless data receiver as well?
ReplyDeleteAnswer: Smart Energy Meter is totally use wireless systems which includes billing system, tamper detection, power consumption management and etc. From this situation, the use and proliferation of RF-EMR will become more higher than usual compared with the electronic energy meter, even it also use wireless system but it not make it as the core system to control all the metering system that may reduce proliferation of RF-EMR. Sometimes old method is much better than new method by only add some of the equipment on the existing energy meter and not change all the existing metering system.
