6 Frequently Asked Questions about “Compensation capacitor and series resonance”
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.
What happens if a series capacitor is compensated?
In electrical networks, the series capacitor compensation can cause a significantly adverse effect called the sub-synchronous resonance (SSR) in which electrical energy is increasingly exchanged with the generator shaft system. This effect may result in damages to the turbine–generator shaft system .
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.
