HOW FAULT INDICATORS WORK
Fault indicators are used to locate earth-faults or short-circuits in power distribution networks. The aim of using fault indicators is to have a reliable, cost efficient and fast indication of the fault location in the network.
In open ring systems, the damaged line section can be disconnected from the network, as soon as a fault is located. While the service team repairs the damaged cable, the rest of the network can be powered up. In this way, the down-time of the network can be minimized to increase the quality of the infrastructure.
But also in radial distribution systems, fault indicators help to locate the faulty cable quickly and cost efficiently without the need of harmful switching operations to locate the fault.
BASIC IDEA OF FAULT CURRENT MEASUREMENT
Every fault indicator, earth-fault and short-circuit indicators, monitors the network constantly. As soon as a fault current higher than the trip value is ***ected, the fault will be indicated.
To avoid wrong indications, most models of fault indicators are analysing the measured fault signal with the help of a microcontroller. Wrong indications caused by peaks, e.g. due to switching operations, will be prevented (setting of response delay).
THE OPEN-RING NETWORK
Normally, the open-ring network of switching substations is supplied by an input via two circuit-breakers. To allow proper fault ***ection, there is one ring main unit with an open switch somewhere in the ring network. To achieve the most accurate and fast localisation of the fault, there should be at least one indicator in every ring main unit. Due to the fact that most of our indicators can be retrofitted, the number of indicators can be easily extended step by step. |
