BKT-3 is designed for control and alternate indication of temperature of three windings and magnetic core of dry-type transformers, which is performed: - conversion of signals of resistance thermocouples into temperature values; - signalling of temperature output of controlled points beyond the set values; - signalling of sensor breakage and short-circuit; - signalling of primary power failure; - information output to the substation monitoring system via standard digital communication interfaces (RS-232, RS-485).
