P154 Non Dir O/c And E/f Relay

We are successfully meeting the requirements of our clients by supplying and trading of the P154 Non Dir O/C And E/F Relay. The 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 over current 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 over current, 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.
