RAGIK is a three-phase overcurrent protection with voltage supervision. It includes overcurrent relays RXIDK 2H, which are permitted to trip only after the generator voltage has dropped below a set value, e.g. 85 % of nominal voltage for a certain set time. RAGIK prevents damage due to accidental energizing to the network. Tripping time is about 30 ms.
