IMCORP’s Factory Grade technology proven 100% effective in identifying workmanship issues and providing Precision Reliability feedback to utility clients and their contractors.
We all know that foreign objects, contamination, or moisture in any medium voltage cable accessory or component will certainly lead to a shortened lifecycle.
An oversight in cleaning and inspecting this 600AMP TBODY during its installation was recently discovered during partial discharge testing at a solar site.
Partial discharge detected, below the manufacturer’s standards led to an inspection of the termination connector which yielded a Hex nut pressed into the wall of the TBODY. That’s right a Hex head nut was causing PD, but maybe more interesting is this had been in service for 2 months prior to IMCORP’s QA testing and had previously passed a VLF test.
Had this cable termination faulted it would have caused the site owners significant financial loss in revenue.
A critical step in the installation is to decontaminate and inspect any medium voltage connections before landing them was clearly missed here!
IMCORP is the technology leader in Medium & High Voltage Power Cable Systems life cycle condition assessment and performance – IMCORP have been helping their clients achieve maximum cable reliability for more than 20 years and have assessed over 130,000 5kV to 500kV cable systems spanning in excess of 160 million feet.
