Conditions for effective ground fault suppression in distribution networks with capacitive current compensation
The paper presents the analysis of main reasons and consequences of the decrease of the efficiency for suppression of single phase-to-ground faults causing dangerous technological failures and faults in distribution networks. Advantages and disadvantages of main systems for partial or full compensation of a ground fault current used for minimizing losses are described. Comparative calculations on the emergency tripping probability due to the development of a single phase-to-ground fault into phase-to-phase short circuit in compensated and ungrounded networks are given. Based on the experience of manufacture and operation, technical requirements to arc suppression devices and their compensation automation systems are developed.
