The double-ended traveling wave (TW) method is a promising tool for fault location on transmission lines. It implies that high-frequency transients during fault inception are recorded in specific devices, which identify the precise time, when a front of an electromagnetic traveling wave reaches the corresponding end of the transmission line. The principles of operation, methods of calculations and test data of the developed traveling wave FL (TWFL) system are presented. The results of field tests and experience of operation of the TWFL system on the double-circuit 220 kV Tommot-Maya transmission line including short-circuit faults caused by lightning strikes are discussed.
