05. Dielectric Testing
GRIDLINK provides annual dielectric testing and inspections at your site or at our location in Thunder Bay, ON by a well-equipped Certified Mechanic with experience in structural inspections and dielectric testing. Properly maintained and tested aerial devices are essential to the safe and economical operation of a fleet. Operators and their co-workers rely on the aerial devices and digger derricks to perform structurally, mechanically, functionally and dielectrically as intended.
Dielectric testing confirms the dielectric integrity of various apparatus. Many tests are conducted by applying a voltage across the “insulator” portion of the apparatus while measuring the resultant leakage current.
GRIDLINK dielectrically tests the following:
- Insulated Ariel Devices and Digger Derricks (RBD’s)
- Live Line Tools (Hotsticks)
- Rigid Cover-up
- Bucket Liners and Jibs
- Pole Guard
