This course is designed to provide delegates with detailed and up-to-date overview of power system protection and relaying. It covers the various faults, their effects and calculations including the effect of faults on equipment; and the earthing system and standard requirement.
The course will also discuss the protection devices and technology including history, construction and principles of protection relays; the IED’s and fuses; the instrument transformers, current and voltage transformers as well as types, construction, performance, specification and applications; the tripping devices of circuit breakers; the mechanism of electric arc breakdown; and the principles & calculation of settings for grading and protection coordination.
Overhead lines and feeder protection including the common types of faults and causes; the proper procedure for transformer protection related to restricted Buchholz relay, overpressure, oil and winding temperature; the proper procedure for motor protection; various electrical and mechanical faults; the various generator data requirements; the types of faults, excitation fault protection and mechanical fault protection; the miscellaneous protection including voltage and frequency protections, bus bar protection; and the circuit breaker failure protection will also be discussed during the course.
