Product Details
Insulator, tester, portable with case, HDE


The Insulator Tester tests energised or de-energised insulators for non-visible internal failures at any AC line voltage.  Detect non-visible insulator failures before they cause operations difficulties or safety threats to linesman.

  • Universal spline for attachment to a hotstick
  • Built-in gigohmmeter applies a current limited 10kVDC potential across an insulator
  • Buzzer provides audible warning of bad insulators
  • LED scale displays the condition of the insulator being tested
  • Powered by an 8VDC rechargeable battery
  • Rugged carrying case included
  • Lightweight - weighs approximately 1.35 kg

The Insulator Tester tests energised or de-energised insulators
for non-visible internal failures at any AC line voltage. These
non-visible failures are known causes of Radio Frequency/
Television Interference (RF/TVI), blinking lights, switchgear
operations and blown fuses. They are also a threat to linesman
safety when performing energised maintenance. Detect
non-visible insulator failures before they cause operations
difficulties or safety threats to linesman.

This product can be hand held for convenient testing of de-energised
insulators in store yards, reclaim areas and in the field just prior to
installation of insulators on the line. The tester is equipped with
a universal spline for use with a hotstick allowing for convenient
energised testing of insulators immediately prior to live line
work. It is capable of testing insulators in a string at all voltage levels.
