Acurate Fault Detection Yields Faster Restoration.

The article focuses on the application of Progress Energy Inc.'s fault-finding radar (FFR) units on its underground cable failures. It notes that these units use time-domain rellectometer (TDR) technology excluding the high-energy cable thumper. They are used as the company's primary means of troubleshooting single-phase underground-cable failures. They also reduce the number of steps required to troubleshoot underground primary loops.
