To make use of the advantages of the various detection methods in different earthfault-situations, the freely programmable earthfault-detection-relay EOR-D makes it possible to select and combine the following earthfault detection methods: Transient-Method with qu-algorithm- up to fault resistance of some kOhm- Restriking and intermittent earthfaultsHarmonics-Method- compare of amounts- Direction of reactive powerWattmetric-Method- Direction of active power- Increase of active currentPulse-Method (=> location in depth)In combination with the PC-Software WinEDC the following functions can be realized: - Parameterization of the relay- Fault-analysis- Net-analysisThe basic unit has been designed for the supervision of up to four feeders; a 19 inch rack can be equipped with up to four relays. Therefore at present up to 16 feeders can be monitored using a 19 inch rack.
