TLDR
Zinc oxide surge arresters are used to replace capacitive elements for voltages below the pick-up voltage of the surge arrester as discussed by the authors, which can provide a high degree of protection against transient disturbances without increasing cost.
Abstract
Zinc oxide surge arresters are used to replace capacitive elements for voltages below the pick-up voltage of the surge arrester. Advantageously, the surge arresters may be provided in an alternating current network to provide a high degree of protection against transient disturbances without increasing cost.
