bioramaniIf the two wave forms are in perfect phase it would work. It may be a better option to individually amplify the signal, rectify and compare.Bioramani sir , how about...

aarthivgac only.But bro what exactly are you using for comparing? op amp ? Microcontroller? And are you using ADC to rectify the AC Currents?

aarthivgi do a similar project, when the ct current exceeds a certain value, this input is given to the micro controller to drive the relay.Are you experimenting on Ac Current...

Now can you tell me which circuit the voltage protection relay makes or breaks , by reading the drawing?

Can the comparator work on AC or do i have to use an ADC in it?
Feb 1, 2012
But i am afraid sir as i have my limits. The CT s are loaded on the first hand and i have to watch that too. Perhaps microcontroller method could...

bioramaniIf you can have shunts on the neutral side of the loads, the two loads being compared can have a common ground. In which case the two shunt voltages can...

I am sorry to be unclear, but i meant the fault is sensed by a relay which furthur trips the breaker. And the other run thing i said because i...

aarthivgpt is just a meter to measure voltage. if circuit breaker is there, we can isolate the pt. and we can even stop the rotation of meter reading. but the...

Plus , this is an 11 kv busbar. What misuse of power can you do on an 11 kv busbar?
