The Greenlee CFT-35 (52087362) Cable Fault Tester Probe is designed for testing leakage current in underground primary voltage cables with two stick voltmeters, including the Double Vision, DigiVolt, MARK and EM series of voltmeters.

The CFT-35 can be used on underground cables with grounded neutrals with a maximum line-to-ground voltage of 21.1kV or maximum line-to-line voltage of 35kV. Operation at higher voltages may damage the CFT-35 and provide erroneous test results.

The CFT-35 is used with a voltmeter/phaser for testing installed or repaired underground cable prior to energizing it. Only cable with extruded dielectric such as rubber or polyethylene can be tested with the CFT-35.
