Differential Relay Testing System

Product Description

Nvis 7095 Differential Relay Testing System is a versatile product for electrical laboratories. It is widely used for differential relay testing and understanding relay protection systems in electrical engineering applications. Various types of relays are used as protection devices in combination with circuit breakers in electrical systems. The Different Relay operates due to differential current flowing in the circuit. When current between two sections varies 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 and understand the differential relay testing procedure used in modern protection systems.

Nvis 7095, Differential Relay Testing System is an ideal platform to enhance education, training, skills & development amongst our young minds. The system is also suitable for practical learning and testing of differential relay in academic and industrial training environments.
