Power Theft Detector

So whenever there is a difference in the amount of power which will be considered as power theft over the line

this is not always true, there are transmission losses, frequency dips, and energy is lost when trees are grounding the line wires ( that's why you would have seen the electricity dept. staff cutting down branches touching the line wires)

so, this method cannot guarantee accuracy.

Thanx Arun for the reply

Even I too agree this method cannot guarnatee acuuracy. Looking art the positive & negatives, the positives of this
1.Power theft can be sensed but not with accuracy
2. Automatic Meter Reading - no need of assessors to go to the house to collect the electrical power reading from the meter.
3. Can be used to detect the other power tampering like Magnetic tampering, Current reversal tampering,Neutral tampering
and the negatives are
1. ya it can be used to sense the power theft....bt is it possible to get the exact location of power theft by saying okkk boss, theft is happening at 20 feet from here....
2. For this system to install, u should change almost current infrastructure of distribution system which is bit complex with the present scenario

3. Is this system is Real Time system ? In the sense (can it perform the task in specific time period given) for eg: People wen do the power theft by putting the metal tap, with in specific time that exact information has to be stored in database for the proof and sent to the power distribution system and that bugger should be caught red hand with proof in no time......is this possible with this system?
4. The system should be general one with high efficiency,easy to install anywhere with the small footprint and of course cost effective... u guyz may or may not be knowing today most of the R&D professionals are not working for creating the new inventions...but working on with the present invention & how to make it cost effective by making use of cheaper technologies.
and I think if we get the solutions for the above said problems it can be procedded ..B-)

Hi Guyz .

I think there is no other way out other than going with TDR for this project. But I am more concerned about the following issues rather than the design problems.

1. TDR technique works on transmission lines with a controlled constant impedance.By its very nature the power distribution system is generally considered to have an uncontrolled variable impedance.

2. For the TDR to work effeciently there should not be much of discontinuities in the transmission lines but in the power distribution lines discontinuities caused by the connectors,joints, Legal taps and EMi caused by the capacitor & inductance fields.

So first we need to have a better solution to overcome these problems
