A Transient Fault Locator for High-Voltage Transmission Lines

Digital simulation of fault location on EHV lines using wideband spread spectrum techniques

“…Spaulding and Diemond [31] describe an EHV line echo-ranger that uses a 1 p-sec DC pulse from a 10 kV source. When a line fault was detected a phase selecting relay system connected the fault locator between the faulted phase and ground.…”
