Single Phase Differential Relay Training System
Single Phase Differential Relay Training System is a versatile product for electrical laboratories. Various types 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 meters with the differential current to perform the experiment with higher stability & accuracy.
