Dielectric Testing


Aerial Manlifts and Digger Derrick Trucks are mobile equipment used by the utility sector to maintain high voltage distribution and transmission systems. The insulated booms of these equipment are mandated to undergo annual dielectric testing to insure they meet electrical insulation compliance. Testing is completed in accordance with the following standards: CSA C225-10, ANSI/ASSE A10.31-2006, and IEEE 978-1984.

FIRTH commonly completes Dielectric Testing in tandem with annual structural inspections to streamline the testing process and minimise equipment downtime.
