Hi,
whether anybody can provide me the circuit for neutral missing tamper at the input of the 3 phase energy meter, where the converter input should be directly derived from the three phase input itself.
Thanks in advance

 

Are you asking for a way to prevent neutral missing tampering or a way to do it?

That is for the power company to handle, not the end user. I suspect the companies have heard of google.

Why would anyone tamper with neutral?
