    Numerical Over Current Relay Testing System

    Nvis 8013

    Product Description

    Numerical Over Current Relay Testing System is a useful platform for Electrical Power System Laboratory. Over Current Relay monitors general balanced overloading and have current/time settings which helps user to understand the different characteristic of over current relay. These settings determine the protective schemes.

    The relay is IDMT type which has different tripping time characteristics with different current conditions. 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.
