This highly innovative machine can be utilized to find out the difference between currents

Demonstration Unit for Differential Over Current Relay

Lab Test

This is a demonstration panel to show the working of “DIfferential OVER CURRENT RELAY”. A protective relay is a device designed to trip a circuit breaker when a fault is detected. The differential current protection relay compares the currents and calculates the difference between the two.

Measurement accuracy (current): 1%

Rating and trip delay programmable through keypad provided on logic controller.

LED’s to indicate area of fault.

Single Phase Variable Voltage Source 0-230V at 1.5 Amps.

Single Phase Transformer 230V/230V at 1.5 Amps.

CTS - 2 Nos.

Over Current Relay settable between @10mA, 50mA, 100mA.

Digital Ammeter – 3 No. for monitoring primary and secondary current and fault current.

Protection Through MCB.

Over Current Relay.

Arrangement to create fault.

The test bench is generally offered as a standard issue, but can be designed as per the customer specs

The test bench is made to demonstrate the working of a Differential Overcurrent relay by simulating a differrential current in an actual relay
