Course Description
Here we deal with the protection & control principles of high voltage stations. HV Bus Differential Protection is studied along with restrictions due to CT saturation & miss-match and its solution, “Restraint Differential Protection”.
Starting with System Faults and how they affect Switchyard Configuration & Elements simple “Differential Protection” is examined along with the mal-operation due to CT saturation and miss-match.
High Voltage Circuit Breakers are examined as to the various Types (Oil, Vacuum, Air Blast, SF6), their Controls (Closing/Tripping/anti-pumping) Reclose Syncrocheck relay CUH 90 – VG as well as Breakers Failure Protection is part of this module along with a quick look at Dynamic Monitoring Equipment. Transfer & remote tripping along with the need to provide immunity from ground rise potential and open circuit situations.
Who this course is for:
- Engineers, Technologists, Technicians, Supervisors & Students.
