CET-2000 Primary Cable Fault Locator - Overview

Haefely Hipotronics CET-2000 Series Capacitive Discharge Primary Cable Fault Locator is designed to fill the requirements between the highly portable 5250 First Response Fault Locating System and the higher voltage / energy CF70 Series Capacitance Discharge Cable Fault Locators. The CET-2000 combines high discharge voltage with high discharge energy to allow location of a wide variety of cable faults, especially when used with a Haefely Hipotronics HV Digital TDR. In addition, the controlled energy capability is quite beneficial for testing of XLPE cable where a lower "thump" voltage but higher energy is best.

The CET-2000 can be used with a high voltage coupler (HVC-4100 Series) and a time domain reflectometer (TDR-1150 or TDR-1170) to quickly provide a specific distance to the fault in feet or meters. This combination of equipment can greatly reduce the amount of high voltage discharge (number of thumps) on a cable resulting in reduced damage or degradation to the cable under test.

The package is very lightweight for the voltage and energy rating which makes for easy installation in all types of vehicles. The standard five feet output cable easily connects to a Haefely Hipotronics 8100 Cable Reel with a lockable MC connector.
