About This Course
Who this course is for:
What you’ll learn:
- Principles of high voltage stations
- System faults
- Switchyard configuration and elements
- HV circuit breakers
- Breakers failure protection
- A solid background in electrical circuitry
Here we deal with the protection and control principles of High Voltage or HV stations. HV Bus Differential Protection is studied along with restrictions due to Current Transformer or CT saturation and mismatch and its solution, “Restraint Differential Protection”.
Starting with System Faults and how they affect Switchyard Configuration and Elements, simple “Differential Protection” is examined along with the mal-operation due to CT saturation and mismatch.
High Voltage Circuit Breakers are examined as to the various Types (Oil, Vacuum, Air Blast, SF6), their Controls (Closing/Tripping/Anti-Pumping) Reclosure Syncrocheck relay CUH 90 – VG. Breakers Failure Protection is part of this module as well along with a quick look at Dynamic Monitoring Equipment, Transfer and remote tripping along with the need to provide immunity from ground rise potential and open circuit situations.
