Insulator Tester Tests for Non-Visible Internal Failures

The Insulator Tester from HD Electric tests energized or de-energized 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, recloser operations and blown fuses. They are also a threat to line crew safety when performing energized maintenance.

Detect non-visible insulator failures before they cause operations difficulties or safety threats to line crews.
