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.
It provides a Constant Current Source. The range and the test current can be set depending upon the range of the MCB. The Tripping time is indicated on Digital Time Interval Meter which stores the information till we reset the system.
Provision is also made in this panel to carry out demonstration of Instanteneous Operation of Short Circuit Protection.
