Product Description
Features
- Software based design
- Instantaneous/Definite time selection
- Wide auxiliary supply
APPLICATION
Over Voltage Relay is used for protection of motors, generators and capacitor banks, feeder etc.
PRINCIPLE OF OPERATION
The Relay, JRV 042, provides Over voltage protection for power systems. The Relay operating time is determined by the set definite time. The relay measures the voltage from input PT and if it exceeds above the set threshold, the relay extends a trip signal after the operating time, which is determined by set definite time. The relay output contacts are self reset type. The TEST button facilitates testing of relay contacts for the trip and alarm circuits.
