    I like the site very much. it is very helpful for any electrical engr. Pls tell me somthing about step potential ant touch potentia and hw its value find out

    I like this site & very useful for electrical engineer. Thank you Mr.Jignesh.Parmar, Pl. tell me about;
    1. Impulse & Short circuit testing of transformer. Are these test done on both winding (H.V. &L.V.), if not why only H.V. winding.
    2. Partial discharge on cables

  4. Gufran Khan says:

    fabulous site, I didnt studies this much in engineering life too

    how do i get a prepaid meter with tamper protection back online

  7. john says:

    i am amazed on how many tampering methods available. are all these working?

    • Ajit Singh says:

      no in the current scenario all method are deducted by meter manufacturers hence all above methods are failed in today time.

  8. manu says:

    Sir , There is no case of neutral disturbance like diode injection please explain how diode injection affect the meter reading

  9. Robert says:

    I’d like to ask the group a question if I may?

    Can a BURNT three phase home meter give a true consumption reading of electricity?

    I am insisting that a Burnt meter needs to be tested and any readings taken from a Burnt meter would be false readings.

    Without testing, the power company is saying that the meter readings are accurate.

    What can I do?

    Can anyone direct me to the literature or links that will prove my case?

    Thank you

    hi there,

    do u have methods to illustrate about electrical theft through digital meter having three phase?

  11. paul says:

    Nice article…thanks for the article. but i would have loved to have the effects of each tamper on the meter measurement and accuracy and suggestion for manufacturer to put measures in place to checkmate them. thanks,

    Jignesh bhai what are you trying to do. We people are already corrupt – please do not add any more corruption. Showing the methods of energy meter tampering do not add any value to any one’s engg. knowledge.

  13. Kanagavalli.B says:

    I have a doubt in current reversal due to reversal of phase and neutral terminals in digital meter can you explain me?

  14. Previously i used to cosumed 250 – 270 KWH units before installation of digital meter After installation of digital electic meter it above 1000KWH unitsWhy is it so high.can you guide me

  15. Bihari Lal says:

    It is a good way of study prevent electrical theft in our distribution in

  16. Munish says:

    Pleasssse… have some common sense. This article will do only more bad than good, if any. That one line disclaimer is just a formality to save your own a$$ you know that!

  17. sobhan says:

    sir full load earth returned(tampered) method, is it done by without opening the seal

  18. Arun says:

    Hi Jignesh, thanks for sharing this wonderful information. I am a Dy. Superintendent of Police from Uttar Pradesh presently posted in Vigilance Unit to prevent Electricity theft.. I would appreciate if you help me personally by giving some more information to us. Please get in touch with me..asap

  19. ganapathi says:

    neutral current reversed figure-b and phase current reversed figure-a are similar or same, could you justify it?

  20. Vikas balichakra says:

    NEAUTRAL DISTURBANCE event on meter if i connected it is reading phase vtg 323V and current 1.5A can u help me y it s reading 323V ????

  21. MH Abbasi says:

    Hello Everyone.I am looking for the article about how to prevent the tempering .

  22. vinoth says:

    Earth + neutral connections is tampered or not

  23. Vinay says:

    1S – > Black wire
    2S -> Yellow wire
    2L-> Red wire
    1L-> Black wire
    Stabilizer is attached on the load and AC is attached with the Stabilizer.
    I just wanted to ask that that whether the above case of current bypass will work here or not.
    Or we have to bypass 2S and 2L.
    Please suggest on the above case.
    I can’t take chance to experiment.
    Do reply on this.
