ADE7754Big problem?
hello;
I have designed three phase energy meter using ADE7754 chip, and I have V.good accuracy in all reading (active power,.....) but I facing big problem
the details :
this digital meter almost works in industrial enviroment which contains machines or contactors, so it can be considered as noise source (Electromagnetic interferences )
these noise effect on the performance of ADE7754 chip and in some cases causes totally damage for the ADE7754
is
I try many times for solve this problem by using chock coil, really it reduce the damage
but not definitly aslo still effect on the performance
so, I want to konw practical methods to remove these noise (meaning that protect the ADE7754 from damage)
waiting reply
thanks
