RELAY AND HIGH VOLTAGE LAB

About Relay and High Voltage Lab

The high-voltage laboratory is equipped with advanced equipment that can be used to test materials and study various high-voltage phenomena. The relay and high voltage laboratory is one of the essential laboratories of the EEE department. The laboratory consists of two parts. First, relay-based experiments are beneficial for identifying and eliminating a large number of errors. The second part includes high-voltage equipment, which works entirely at a high voltage of approximately 140 kV.

Practicals/experiments carried out in Lab:

1. . IDMT non-directional characteristics and calculation of error in operating time for Over – current Relay (Electro – mechanical type)
2. Operating characteristics of Over – voltage & Under- voltage Relay (Electro – mechanical type).
3. Operating characteristics of Microprocessor – based (numeric) Over / Under - voltage Relay.
4. Operating Characteristics of Microprocessor Based (Numeric) Over –Current Relay.
5. Motor protection scheme Studies.
6. Spark over characteristics of air insulation subjected to High Voltage AC – with Spark over voltage corrected to STP.
7. Spark over characteristics of air insulation subjected to High Voltage DC.
