Over Current Relay Testing System is a useful learning product for electrical laboratories. Over Current Relay a monitor general balanced overloading and has current/time settings.

These settings determine the protective schemes. The relay is IDMT type which has different tripping time characteristics with different current conditions. These are classified in accordance with their characteristic curves which indicate the speed of tripping operation.

The typical setting for relay is 0.5-2 Amp in 1-10 seconds. Has accurate voltage, current and time measurement. It includes built-in variable supply, digital voltmeter, ammeter, and timer.

The timer operation is automatic when current is applied to relay. This automatic operation ensures accurate tripping time measurement.
