Protection and Control of High Voltage Power Circuits
This course deals with the protection and control principles of high voltage power stations and major equipment like transformers, circuit breakers, CTs and VTs. Instantaneous, overcurrent and transformer differential protection are studied. 10 sections in 5h 23min total course length.
Course Description
This course deals with the protection and control principles of high voltage stations. Starting with system faults and how they affect switchyard configuration and elements, simple “Differential Protection” is examined along with the maloperation due to CT saturation and mismatch.
High voltage circuit breakers are examined as to the various Types (Oil, Vacuum, Air Blast, SF6) and their closing, tripping, and anti-pumping controls.
The course will pay attention to the Reclosure Syncrocheck relay, as well as Breakers Failure Protection and Dynamic Monitoring Equipment. Transfer and remote tripping are discussed along with the need to provide immunity from ground rise potential and open-circuit situations.
