Nvis 7095 Differential Relay Testing System

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

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.
