Example-3:
For the power system shown below calculate overcurrent and earth fault relay
settings in respect of both transformer HV and LV side relays using approximate
or quick method.
Transformers are operating in
parallel. LV side relay has Directional as well as Non-Directional element.
As recommended in topic explaining
approximate method for calculations of relay settings; readers are requested to
go through calculations steps preferably by hand calculations.
