Klein Tools HVNCVT-1 Dual Range High Voltage Tester

Yes. The HVNCVT-1 is a non-contact high voltage tester built to check for the presence of voltage in overhead conductors and to trace faults in cables. Its HIGH range covers 1.5kV AC to 132kV AC, which is the range utility and line work lives in. Voltage is signalled both audibly and visually, so you get confirmation without taking your eyes off the conductor.

It will. The LOW range on the HVNCVT-1 runs from 50V AC up to 1.5kV AC, which covers 120V, 208V, 240V and 277V branch circuits as well as 480V gear. Switch to the HIGH range (1.5kV to 132kV AC) for primary and overhead work. That dual range is what separates it from a standard low-voltage pen tester that stops around 1000V.

No separate battery purchase needed to get started. The HVNCVT-1 ships with one 9 volt battery and a carrying case. Keep spare 9V cells on the truck, since that is the only power source the tester uses.

Pick based on the highest voltage you work near. A standard NCV pen is fine if you never leave branch circuits and panels. The HVNCVT-1 makes sense when the same crew touches both worlds: 50V AC to 1.5kV AC on the low range for building wiring, and 1.5kV AC to 132kV AC on the high range for overhead conductors and cable fault tracing. Buying the dual range means one tool instead of two.

Order Klein Tools HVNCVT-1. That is the manufacturer part number for the dual range high voltage tester, and it is a single-model item with no finish, length, or range variations to specify.

Yes, fault location in cables is one of the two uses Klein states for the HVNCVT-1, alongside checking overhead conductors for voltage. You work along the run and the tester signals audibly and visually where voltage is present, which lets you narrow down where it stops.
