what are the settings is there for ABB REM543 Generator
Protection Relay
GENERALLY,WHEN THE COMMISSIONNG IS DONE WITH SHORT CIRCUIT
TEST, ALL PARAMETERS ARE SET FOR ALL PROTECTION RELAYS-
NAMELY: i) differential protection
ii) Over current,instantaneous over current
iii) Unbalanced current ( negative sequence)
iv) loss of ecxcitation.
v) reverse power
vi) Under voltage.
viii) over voltage
hence it is not necessary to repeat .
