- Calculate IDMT over Current Relay Setting (50/51) October 11. I’m working on Overcurrent relay setting of Primary Transformer Protection (2000KVA with 6% impedance) with 200/5 CT ratio. Compare and contrast these same calculation with the ones done to get the settings of an REJ603 ABB protection relay? I would really appreciate.

We’ll be looking at Directional Overcurrent relays from a testing perspective in this post. Successful Directional Overcurrent tests have three parts: Your current must be above the pickup setting. Your current must be in the correct direction. You must have a polarizing signal.
In the previous post about Directional Overcurrent relay (67) testing , we reviewed Directional Overcurrent protection from a system perspective to enhance the descriptions in.
