This work introduces a differential protection method for early detection of a fault in a single-capacitor into a capacitor bank configuration. This protection has the aim to discriminate between internal faults from transient conditions such as capacitor bank energisation.
How does a capacitor unbalance protection work?
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.

Series capacitor protection function
Series‐compensated transmission lines utilize series capacitors to cancel a portion of the inductive reactance of the line, thereby improving the power transmission capability of the line.
FAQs about Series capacitor protection function
Do series capacitors affect the overall protection used on series compensated lines?
A discussion of their effect on the overall protection used on series compensated lines. First, however, a brief review will be presented on the application and protection of series capacitors. Series capacitors are applied to negate a percentage of and hence reduce the overall inductive reac-tance of a transmission line.
Why are series capacitors used in transmission systems?
Load Division among Parallel Line – Series capacitors are used in transmission systems for improving the load division between parallel lines. When the new line with large power transfer capability is paralleled with an already existing line, then it is difficult to load the new line without overloading the old line.
What is a series capacitor bank?
Series capacitor banks consist mainly of the capacitors as well as their protection system and function to increase power flow on an existing system by reducing line impedance. Their first application dates back to 1928 when GE installed such a bank – rated 1.2 MVar – at the Ballston Spa Substation on the 33 kV grid of New York Power and Light.
