This is a demonstration panel to show the working of “DIfferential OVER CURRENT RELAY”. A protective relay is a device designed to trip a circuit breaker when a fault is detected. The differential current protection relay compares the currents and calculates the difference between the two.
This is a demonstration panel to show the working of “DISTANCE OVER CURRENT RELAY”. A protective relay is a device designed to trip a circuit breaker when a fault is detected. The distance current protection relay is a type of relay which functions depending upon the distance of fault in the line. More specifically, the relay operates depending upon the impedance between the point of fault and the point where relay is installed. These relays are known as distance relay or impedance relay
Protection has assumed a large importance in the power industry in the recent years. This protection involves the use of relays on a large scale. Relays are basically used to give commands to circuit breakers, contactors, etc by sensing different parameters like current, voltage, etc. Just as electrical circuits may range from a few watts to 100 megawatts, the size and rating of the relays vary considerably. Study of relays is now being included in the engineering curriculum. M/S SCR Elektroniks have developed demonstration units for different types of relays such as under protection/over protection relay, temperature protection relay, motor protection relays, AC/DC relays and contactors keeping the engineering curriculum in view.

This is a demonstration panel to show the working of “DIRECTIONAL OVER CURRENT RELAY”. A protective relay is a device designed to trip a circuit breaker when a fault is detected.
A directional relay uses an additional polarizing source of voltage or current to determine the direction of a fault. The fault can be located upstream or downstream of the relay’s location, allowing appropriate protective devices to be operated inside or outside of the zone of protection.
