Our smallest VLF model, t he VLF-28CM approaches the size and cost of a DC hipot and is desig ned for quick & easy short-run cable testing. It can test up to 0.4 μF of load, or up to 4000 feet (1200 m) of a typical 15 kV class cable. Small, light, inexpensive. Now there is no reas on not to use VLF

Tan Delta testing (or Tan δ/Dissipation Factor/Loss Angle) is a non-destructive diagnostic test performed to measure the condition, or level of deterioration, of a cable systems insulation. A population of cables is tested and graded. A comparative analysis is then made to predict relative life expectancy and to help prioritize cable replacement, rejuvenation/injection, or to determine what further tests may be useful, possibly a VLF Withstand or VLF Partial Discharge test.

The TDB-60 is used for measuring the loss angle, or dissipation factor, of shielded power cable. These measurements are used to track the deterioration of cable insulation. Increasing Tan Delta numbers indicate increasing cable insulation degradation. TD measurements are used to establish baseline readings on new installations, for trending cable condition over time, and to help prioritize cable replacement and/ or cable injection programs.

The PFT Series of AC hipots are ideal for testing many types of substation apparatus, motors/generators, isophase bus, and other loads requiring an AC withstand test. The HVI AC hipots are among the smallest, lightest, and most economical available while delivering higher power ratings and features not found elsewhere. For example: the PFT-503CM is the only single piece, 50 kVac @ 3 kVA, shielded cable output hipot produced, used worldwide for testing vacuum bottles, switchgear, reclosures, circuit breakers, etc.

Booms & Liners HVI produces several AC testers to cover all boom and liner testing, with models available up to 300 kVac for boom testing and 10 kVA for liner testing. The popular ALT-120/60, designed to meet ANSI A92.2 testing, is the most powerful and full featured standard aerial lift tester available. It delivers up to 120 kV for boom testing and up to 7 kVA of power for testing nearly all liners and other high capacitance loads requiring an AC withstand test. For DC voltage testing, see the PTS Series of DC Hipots for our highly popular PTS-100. The 0-60 kVac/0-120 kVac model ALT-120/60 provides a higher power rating than others: 7 kVA capacitive for one hour - 4 kVA resistive continuous duty. It offers a 250 uA current meter range, rugged, transit protected, anti-static glass front meters, a guard/ground circuit, test timer, and an internal voltmeter divider. There is no better truck tester.
