Differential Relay Testing System

Nvis 7095 Differential Relay Testing System is a versatile product for electrical laboratories. Various type of relays are used as protection devices in combination with circuit breaker in electrical system. The Different Relay operates due to differential current flowing in the circuit. When current between two sections vary from a known and permissible value, the relay gets tripped and protects the connected device.

The Differential Relay requires two current sources for its operating & testing. For this, two current injection units are provided with the system. The current of both the injection units are displayed on LCD with the differential current to perform the experiment with higher stability & accuracy. The students can understand the working of differential relay by measuring the operating characteristics. They can also learn the connection of this protection device in the electrical circuit.

Nvis 7095, Differential Relay Testing System is an ideal platform to enhance education, training, skills & development amongs our young minds.
