Shunt capacitor switching in distribution and transmission systems

Summary

The performance of switchgear for capacitor banks in service is compared with their performance during type testing. A survey interrogated capacitor size, switching rates and maintenance practices. For SF₆ and vacuum devices, state-of-the-art was collected on the probability of restrikes in relation to inrush current and frequency aiming on electrical endurance. Alternative devices are described and peculiarities of filter bank switching.
