Protection and Control of High Voltage Power Circuits
Learn about the principles of high voltage station protection and control. Study HV Bus Differential Protection and its solution, Restraint Differential Protection. Explore System Faults, Switchyard Configuration Elements, and various types of HV Circuit Breakers. This course is ideal for Engineers, Technologists, Technicians, Supervisors, and Students.
What you’ll learn
- 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 & mis-match and its solution, “Restraint Differential Protection”.
- System Faults; Switchyard Configuration & Elements; The DESN Station (Duel Element Spot Network); HV Bus Differential Protection; CT Saturation & Mal-operation of Bus Protection; CT Saturation & Restraint Differential Protection; Westinghouse KD – 4 Relay; Surge Protective Devices; Fuses; DC Protection; Logic Differential Protection; The Modern IED Relays (Intelligent Electronic Device); Overview HV Circuit Breaker Types (Oil, Vacuum, Air Blast, SF6); HV Circuit Breaker Controls (Closing & Tripping); HV Circuit Breakers; Reclosing (Syncrocheck CUH 90 – VG Relay); Dynamic Monitoring Equipment (DME); Impedance Relaying (POTT)
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 & mis-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 mis-match.
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 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.
