Hi
I am working on Reyroll 2B3 High Impedance Earth Fault Relay. The information i got that relay is fixed at 20mA with Voltage setting form 15V to 250V. I have to present the characteristic of this relay on time current characteristic Graph. Could anybody please tell me that how i can show that on TCC?
Regards

Why would you want to show it on a TCC? It's an instantaneous - in so far as anything is instantaneous - unit protection relay. You wouldn't normally expect it to coordinate on a time / current basis with anything else. If there's an in-zone fault greater than setting current it trips immediately, otherwise it remains stable.
