IR Inspection

Thermography can be performed to locate any potential heating issues and circulating ground currents in your bus duct system.

Visual Inspection

Visual inspection of the bus system exterior is performed to determine general condition and locate areas of concern for future inspection.


General Condition Assessment (Level 1)

A condition assessment inspection is a minimally invasive inspection used to follow up online testing if no major areas of concern are found.

Offline Inspection & Maintenance (Level 2)

During a full offline inspection, all accessible interior and exterior areas of the bus are inspected and primary components cleaned by hand, including insulators, flexible braids

and bushings.

Cryogenic Cleaning (Level 3)

If a significant buildup of debris and contamination is expected or carbon from arcing is present, cryogenic cleaning can be performed to thoroughly clean the interior of the bus.
