Electrical Protection & Relay Systems

Principles and application of electrical protection systems including overcurrent, earth fault, and differential protection, with hands-on relay configuration and secondary injection testing.

What you will learn

• Explain protection system zones, grading principles, and the operating characteristics of overcurrent relays
• Configure IDMT overcurrent and earth fault relay settings using time-current characteristic curves
• Test protection relays using secondary injection equipment and verify trip times against settings
• Coordinate protection settings across a radial distribution network to limit the extent of supply interruption

Who it's for

FET electrical engineering students with knowledge of three-phase systems and distribution networks.
