Substation Power Engineering Fundamentals

Description

Dear All,

Welcome to our course “The Substation Fundamentals Course”. A power substation is an essential part of an electrical generation, transmission, and distribution system. The assembly of apparatus used to change some characteristics (e.g. voltage, frequency, p.f., A.C. to D.C., etc.) of an electrical supply is called a substation.

Power substations have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network. Smaller distribution stations may use recloser circuit breakers or fuses for the protection of distribution circuits.

Substations themselves do not usually have generators, although a power plant may have a substation nearby. Other devices such as capacitors and voltage regulators may also be located at a substation.

This course consists of 9 Hours of recording and total of 95 different topics.
