---PROTECTION OVERVIEW---
Protection relays in the Uni-line range consist of a complete series of generator protection relays. The range includes relays for monitoring of voltage, frequency, current, overload, reverse power, excitation failure, stator earth fault failures and loss of mains relays.
All relays have been approved by major classification societies. Please refer to the data sheets for exact details.
