The Essentials of Capacitor Banks: Connections, Calculations and Relay Protection

Course Description

This course is one of the essential courses for electrical engineers. It explains the theory behind capacitor banks, their series and parallel connections, protection and much more. The course is based on the use of capacitor banks in the field.

The course consists of 8 lessons in 1 hour 41 min.

Why in series connection capacitance decreases but still, they are used in the field? This question and many others are answered in this course. You will learn the advantages of capacitor banks as well as the important concept of the current transformer and the meaning of its primary and secondary values.

This course answers the most common questions related to capacitor banks:

Do capacitors provide fixed MVAR all the time?
How to discharge a capacitor, charging and discharging of the capacitor, time constant.
Checking relationship among capacitance, charge, and voltage applied.
How to calculate voltage rise when a capacitor is switched on?
How capacitors are connected in capacitor banks?
How to apply unbalance voltage and current protection schemes?
How to calculate phase overcurrent, earth fault, and neutral current displacement relay settings of capacitors?
