The device will connect to the network and establish the network source impedance from small-scale disturbances or perturbations resulting from transformer tap changer operations. This impedance can accurately be correlated to a true network fault level for that location, providing near real-time information to planning engineers. This tool would also facilitate the connection of distributed generation by establishing if the proposal would exceed the fault level rating of the feeder or line.
This project was co-ordinated by the ENA and aimed to develop an on-line instrument that can successfully measure/estimate the fault level on a distribution network with repeatability and reliability. The instrument is to be based on the EA Technology Extended Supply Monitor.
