Portable Primary Cable Fault Locator

More Information


The 5250 primary cable fault locating system meets the demanding needs of electric utilities, electrical contractors, or any company testing medium to high voltage cables that require a highly portable, easy-to-use thumper system for quickly restoring electric service.The 5250 utilizes an innovative, time domain reflectometer (TDR) along with the highest energy, battery-operated thumper on the market. The 5250 will reduce cable fault locating time by up to 80%. The 5250 can test faulted, loop feed underground residential distribution (URD) cable systems without having to disconnect transformers in an effort to sectionalize the cable fault between two transformers.The battery powered 5250 combines a capacitive discharge, high voltage filter, digital TDR, and battery charger into one complete package. The operator can control all test functions through the digital TDR or by using the analog, high voltage controls on the 5250 front panel. The 5250 is connected to the cable under test using quick clamps and MC adaptors. Once the 5250 primary cable fault locator is connected to the cable under test, a trained operator can find faults in a matter of minutes.
