Tracking Found on Insulated Bus

Medium voltage bus duct is often the most neglected portion of the electrical system, due to the difficulty of isolating the equipment and the lack of useful test methods.

The IQ Program provides you with magnetic sensors that attach to the outside of the bus duct enclosure to detect these types of harmful defects, while the equipment remains in service.

Bus Duct Clearance Problem

Another medium voltage bus duct problem discovered with the IQ Program. In this case, the heater strip conduit was encroaching the electrical field of the right-most bus, causing partial discharges.
