CHARACTERISTIC CURVES DESCRIPTION OF PROTECTION FUNCTIONS ANC 303 (AN Series) relay is a functional relay (Current unbalance protection and IDMT Over current protection etc) designed to be used for the protection of capacitor banks. Capacitor banks are used in the power system for compensating the reactive power and for filtering harmonics. The capacitor banks are usually protected against overload caused by internal faults in the bank.
