“High powered 120 kVac @ 7 kVA hipot (200 kVac & 300 kVac models are available)”

TThe unrivalled power to weight ratio of the ALT-120/60 makes it the most powerful truly portable AC Hipot on the market. With a rating of 7kVA and continually adjustable AC output up to 120kV the ALT-120/60 is an extremely versatile AC test set. This versatility and a very generous duty cycle allows for numerous sequential tests and extended time testing applications on equipment such as:


  • Switchgear
  • Bucket trucks and liners (designed for ANSI A92.2)
  • Insulated work platforms
  • Bushings
  • Circuit breakers
  • Reclosers
  • Overhead apparatus
  • Hot sticks
  • Fuses
  • Arrestors
  • Motor windings
  • Bus ducts
  • Rubber products
  • Insulators
