In early spring 2012 four companies were invited to demonstrate their “traveling wave” fault location devices by an Asian utility.
The demonstration would take the form of a test where the utility would induce 5 faults at different locations on a live 115kV transmission network. Each company would have 2 days to install their equipment and on the third day the faults would be induced.
On that third day the four companies would be placed in a room with remote access to their devices. As each fault occurred they would be asked to communicate to their respective units and give the “distance to fault”. The live faults were performed on 13th of May 2012.
