Description
This is an intermediate to advance level course dedicated to schematics and control wiring diagrams of high-voltage and medium-voltage circuit breakers. The course starts with explaining circuit breaker cubicle schematics and control wiring diagrams and continues with discussing each circuit in detail.
Wiring diagrams (panel wiring diagrams, control wiring diagrams) provide a road map of the connections between circuit breakers and other devices (disconnectors, CTs, VTs, etc.) to facilitate assembly, debugging, and testing. It’s very important to fully understand every detail you can find on these schematics.
After completing this course, you will be able to easily read and analyse the control and protection schematics of any substation or power plant (GIS, LCC, Switchyard, etc.).
