To introduce various concepts and applications of protection relays


Introduction to Protection

Purpose, principles, requirements and components of protection systems. Zone of protection; unit and non-unit protections; main and backup protections. What relays must do and must not do.

The Most Basic Form of Protection

Differences between overload and overcurrent protections. Instantaneous, timedelayed and IDMT overcurrent-earth fault (OCEF) protection relays. Characteristics and settings of OCEF relays and fuses. Discrimination of protective devices.

Concept of Differential Protection

Features and drawbacks of differential protection. Need to ensure that the relay does not operate wrongly during loads, switching conditions and external faults. Application of differential protection to power transformers. Protection of Medium Voltage Equipment Differences between protection of high, medium and low voltage electrical systems. Protection of cables, transformers, motors and generators.
