Protective Relays: Basic Relays, Electromagnetic Attraction Relays, Induction Relays, Relay timing. Time P.S.M. curve, Calculation of relay operating time, Functional relay types. Protection of Generators: Differential protection of Generators, modified Differential Protection for Generators, Balanced Earth Fault Protection, Stator Interturn Protection, Bus-bar Protection: Protection of Lines, Time Graded Overcurrent Protection, Differential pilot-wire Protection, Distance Protection. Grounding or Earthing: System Grounding, Ungrounded Neutral System, Neutral Grounding, Solid Resistance Grounding, Reactance Grounding, Arc Suppression Coil Grounding (or Resonant Grounding), Voltage Transformer Earthing, Grounding Transformer.

Goals

This module develops a thorough understanding of protection and switchgear requirements for high-voltage electrical power systems. On completion of this module the learner will/should be able to; 1. Discuss the requirements of substation equipment and their design. 2. Specify and evaluate the requirements of substation protection systems. 3. Appraise transmission line parameters and configurations, their design and protection. 4. Design protection systems for generators, lines and busbars. 5. Specify grounding systems for power systems with an emphasis on neutral grounding.
