RET670 transformer differential protection relay testing calculations

[@muhammadezzat2853]

I have a problem regarding power measurements the relay reads all currents and voltage correctly but power gives values that not match with injection

[@Powersystemengineeringsolution]

Check relay setting current and voltage and frequency and wiring connections, injection source measurements
