JRV 062 064 Neutral displacement relay 144 sq mm

Features

• Software based design
• Instantaneous/Definite time selection
• Wide setting range
• Wide auxiliary supply

Principle of Operation:

The sensing Voltage is applied to the input terminals of the relay. The applied voltage is amplified and fed to a Voltage Comparator. Output of the comparator is applied to the processor. The Program residing in the CPU performs the function of measurement and extends a trip signal after the set time delay is reached. The Relay contacts are self reset type and indications are latched, RESET button provided on the front of relay to clear these latched indications. TEST button is provided to test the relay contacts for trip and alarm circuits.

Application:

Earth fault protection in transformer generator motor and capacitor banks.
