Insulated aerial lifts are designed to better protect an operator from electrocution. To ensure electrical insulation is working correctly, lifts should undergo dielectric testing.

Dielectric testing is a non-destructive method of testing the insulation’s ability to resist a high voltage charge. Aerial lift manufacturers will determine a recommended frequency of testing but units should also be tested after repairs and after contact with power lines.
