    摘要: A grounding arrangement for a normally ungrounded multi-phase powerline system, which also carries dc information signals. A resistance and a spark gap device are provided in a path between system neutral and a ground. Upon the occurrence of a predetermined fault condition the spark gap device will conduct, and if the voltage developed across the resistance is of a predetermined value, a current bypass path is established around the spark gap device after a predetermined time delay.
