DC Injection in Energy Meter

Anything that may encourage illegal, unethical and immoral practice is not discussed on CR4,

I realize the English is likely not your primary language, but you don't give us much to work with here. Do you want us to guess which of the thousands of Energy Meters you are using and how a DC injection might be used? For all I know you may actually have a calorimeter that has an auxiliary DC output to power optional circuits.

It makes the energy meter give a false reading, and is probably illegal.

anything that screws a 'lecy company is OK by me

So maybe they should stop delivering "'lecy" to you then...

It's entirely possible this is a legitimate issue, as evidenced by this:

I did not buy and read this paper, but the abstract certainly raises a legitimate connection to the OP's initial cryptic question. So let's not jump to conclusions here.

Don't use saints for illegal purpose !

Dear Group Members, I am surprised to see the response! For my energy meter application, I just want to understand how to trap the DC injection tampering case. For all this, If I know How DC injection affects the normal functioning of the Energy Meter, I would design the better algorithm to trap this tampering case. What all parameters get affected in energy meters primary & secondary current channel and/or magnetic field which points to DC Injection tampering case. So for all this; I am asking saints to help & build my understanding for DC Injection.

Its good that you come back with clarifications, I hope now you will realize the importance of making post with the full details and correctly phrased, I advice you to post your question again with best possible way can do I am sure you get better response,

Good luck

Dear Group Memebr, As suggested by fellow member "Rakesh_semwal", I am posting my question again: I am working on smart energy metering solution where I am trying to trap all possible tampering cases as and when it happens. In align to above mentioned objective, I am trying to understand "How DC injection affects the normal functioning of the Electronic Energy Meter". To trap the DC injection in energy meter tamper case, I need to understand What all parameters get affected in energy meter primary & secondary current channel and/or magnetic field which points to DC Injection tampering case. If I gain the "DC injection in Energy Meter" understanding, I would design my algorithm to trap DC injection tamper case in better way. Thanks in Advance!

You're surprised to see the response! You provide insufficient information to know what kind of energy meter readings your concerned about but you imply that it involves an illegal activity by using the word "tampering". I'm surprised to see that you are actually interested in discussing this illegal activity. You now claim to be interested in thwarting this illegal activity by understanding how it works. Well guess what, I don't believe you. I don't believe you because you are hiding behind two layers of anonymity in not even posting with a registered handle here. I don't believe you because anybody actually trying to stop people from succeeding in doing this illegal activity will not discuss when it does and does not work on a public forum.

Dear friends, With True spirit of not Offending to any friends! I guess we are missing an important essence of public forum to share the knowledge rather than believing in someone's credentials. May be the Guy who has joined this forum is very new to this group and not versed with DO and DON'T of this forum. Few days back only i joined this group while searching for Maximum Demand and Demand Reset concept. I realized this is a great forum to discuss/share core technical stuffs. To discourage anonymous posting, let the admin disable the anonymous posting option or discourage non-credential people to join this forum.

The context in which the original question exists requires more than one sentence in the original posting. The fuller the original post is in terms of information and context, the fewer will be the number of WAGs to it by the underinformed and the less chance there will be to experience and write about disappointment.
