The ADR141A is a 3 OC and 1 EF relay with Instantaneous high set and programmable output to simplify feeder protection wiring. The ADR141A continuously monitors all 3 phases and earth current, through CT connections. The high high-speed micro-controller samples this current through a 12-bit A/D converter. The micro micro-controller performs powerful Digital Algorithms to find out Amplitude of current signal, and then this value is use for protection and metering function. All measurement is tuned to fundamental frequency. Each input current is also also displayed on 16 x 2 LCD display for metering. The Relay is having main three functions 1) Protection 2) Self Self-Supervision Supervision 3) Measurement The Relay can be supplied with different model. It can be either Definite Time or IDMT.
