Aerial Lift Testers

Aerial Lift Testers

ALT Series

HVI produces AC voltage testers that perform boom and liner testing, with models available up to 300 kV AC for boom testing and 10 kVA for liner testingThe ALT Series is designed for AC voltage testing aerial lift devices. The standard models available are rated 120/60 kV AC, 200 kV AC, and 300 kV AC, rated up to 7 kVA.

The popular ALT-120/60 is the most powerful and full-featured standard aerial lift tester available. It was initially designed for testing bucket truck booms and liners, but its dual output voltages, high power rating, and mobility make it ideal for field testing other high capacitance loads requiring AC withstand testing.

0 – 120 kV AC
0 – 60 kV AC

0 – 210 kV AC
0 – 50 kV AC

0 – 300 kV AC

Output cable sold separately.
Double liner testing option available.
CE marked models are available.
The ALT Series is not partial discharge (PD) free. For PD free AC hipots, see the HPA Series.

For liner testing, choose our 50 kVac @ 10 kVA hipot from our HPA Series. For testing the hydraulic fluid in the booms, see our DTS Series.

PTS Series

For DC voltage testing, the PTS Series includes the popular PTS-100U, which can be equipped with a 50’ (20 m) shielded output cable for boom testing.

100 kVdc @ 10 mA
