The Agile P154 relay provides non directional overcurrent and earth fault for MV/LV and HV backup feeder protection. The relay features a wide range of measurement, protection and monitoring functions and is easily customizable using programmable BI/BO/LEDs/AND logic. The P154 is economical, designed for deployment in volume in lower voltage systems, as a backup relay in HV systems, or as direct refurbishment of non-communicating overcurrent relays.
The principal protection functions are timed and instantaneous phase and earth fault protection, with up to 3 independent stages available. Additional versatility is provided through negative sequence overcurrent, thermal overload, cold load pickup, inrush blocking, broken conductor, breaker fail, restricted earth fault, undercurrent/loss of load, and trip circuit supervision functions. The hardware capability is broadened by a sensitive earth fault CT option, and a universal auxiliary power supply range to permit standardization in procurement and inventories.
