HIGHLY ACCURATE FAULT LOCATION APPLIED TO SUB TRANSMISSION NETWORKS AND CABLES

摘要

Due to the accuracy and consistency of distance to fault results, travelling wave fault location is becoming more widely used. Virtually all installations to date have been at the transmission level where it is normal to have more than one circuit connected to a busbar. As such, it has been possible to base the travelling wave systems (TWS) fault location on current transients derived from the secondary of the protection CT.
