Microprocessor Voltage Relay

This kit consists of an L&T make microprocessor based voltage relay. The connections are brought to front panel through terminals. Toggle switches are provided to select trip voltage, trip time and trip time characteristics. The voltage range is fixed at 240V. The kit is provided with a voltage source capable of supplying voltage upto 500V. A digital AC voltmeter is provided to indicate voltage and a time interval meter is provided to measure the time taken by the relay to trip. A switch is provided to switch between setting the relay and testing the relay along with indicators.
