Title: Ring main distribution network circuit - achieves staggered time selective protection by use of relays and switches avoiding use of additional control cables
Inventor: EGLI ERNST
IPC: H02H7/28
Filed: 1977-03-02
Abstract: The protection system employs non-directional max. current-time relays. At least one relay and its associated switch operates instantaneously and divides the ring main into two sections each with one feed and a number of radial spurs. The remaining relays have timers and logic circuits associated with them and are in two groups. The operation of the first group is blocked if the over-current signal is eliminated within a fixed time before operation of the relay. Operation of the second group is blocked if the section voltage is not below a critical value indicative of a fault. The delay on the second group is sufficient to allow automatic reclosure of the section splitting switch. By suitable staggering of operating times the faulted circuit can be isolated typically within 1 second.
