Combined Power Supply BPK-5-T for Uninterrupted Relay Protection Applications

BPK-5-T are designed to provide uninterrupted power supply to relay protection and automation devices (RPA) and circuit breaker drives at power facilities with alternating operating current, not equipped with guaranteed voltage sources. BPC-5-T together with RPA devices are designed for installation on control boards, panels, in relay cabinets of complete switchgears (CRU) and control panels of power stations and substations. BPC-5-T provide power supply of RPA device and circuit breaker drive with rectified current, both in normal and emergency modes of operation of electric networks in case of all types of short circuits accompanied by voltage reduction. BPC-5-T have different output voltages. BPC-5-T have the function of power supply from the current transformer circuit.
