Cable fault locator EZ-THUMP™ V3

The EZ-Thump 12 kV makes accurate fault finding on underground MV distribution power cables quick and easy The EZ-Thump 12 kV, model v3, cable fault location system makes fault finding on underground MV power cables easier than ever! This all-in-one fault locator has been designed specifically to be readily transportable – it will fit into an average-sized car – and easy to operate, even for inexperienced users. The EZ-Thump 12 kV is an ideal choice for first responders and its extensive capabilities make it well-suited to more demanding applications. The EZ-Thump 12 kV incorporates a single-stage capacitor surge discharge system that delivers 500 J at 12 kV. An integrated time-domain reflectometer (TDR) facilitates the pre-location of low resistance faults and, by using the Arc Reflection Method (ARM), high resistance faults. In addition, the EZ-Thump 12 kV can be used in conjunction with an acoustic/electromagnetic receiver, such as the DigiPhone 2, to pinpoint the precise location of faults. Sheath testing and sheath fault location are also supported. The instrument includes advanced safety features as standard, such as the F-OHM system that automatically checks that earth/ground connections have been made correctly and, if detects a problem, will inhibit testing. It also has an emergency stop function and a key-switch safety interlock. All of the instrument’s functions are controlled with a single rotary knob and the test results are shown on a bright colour display that is easy to read even in bright sunlight. No settings are needed when the instrument is used in automatic mode; users connect the test set to the cable and switch it on.
