This masterclass course provides a deep understanding and knowledge in power substations. You will learn different substation types, their differences, electrical equipment (switchgear, transformers, breakers, isolators, etc.), as well as busbar schematics and relay protection principles. The course consists in 97 topics and 9h 2min total length.
Course Description
This masterclass course provides a deep understanding and knowledge in power substations. You will learn the most common substation equipment such as switchgear, transformers, isolators, earth switch, CTs & VTs, shunt reactor, batteries and others.
The great attention is given to the busbar schemes (configurations), transformer protection and substation relay control & protection.
The course consists in 22 lessons, 97 lessons and 9h 2min total length.
The course starts with discussing three most common substation types (air-insulated, gas-insulated, and hybrid), their comparison in working principle and layout. You will learn the main components installed in most of substations, such as switchgear, transformers, isolators, earth switches, instrument transformers (CTs, VTs), fuses, capacitor banks, shunt reactors and many others.
You will learn about batteries installed in power substation, charger techniques and how to depict batteries in a single-line diagram.
The next big chapter will cover the most common busbar configurations and layouts, such as single-Bus single-breaker scheme (with and without Bus Section CB), double-bus single-breaker scheme, one-and-half breaker scheme, ring or mesh busbar scheme and few others.
In the the next chapter will explain in great detail relay protection in power substation. We will start with a philosophy and characteristics of control and protection systems. You will learn ANSI Codes for protection devices and faults in power system.
You will learn all the types of protection relays, tripping relays, lockout relays, auxiliary relays and tripping coils.
Finally, we’ll discuss a medium voltage switchgear and all its compartments. You will also learn the essentials about substation earthing.
