We addressed identified issues with a suite of targeted solutions. Red failed stickers were affixed to the two breakers with malfunctioning trip units, signaling the need for replacement. On the WL breaker, a comprehensive remedy was applied with the installation of a new charging switch, ensuring seamless manual charging.
Transitioning to the SBS breakers, a thorough restoration process was undertaken, involving oiling and cleaning to reinstate optimal functionality. In the case of SACE breakers, we advocated for a retest utilizing an alternative secondary injector, and in the event of a failed retest, recommended primary injection to verify the trip unit’s reliability.
As for the medium voltage breakers, our technical experts conducted a hands-on intervention, correcting the charging mechanism internally. To validate the resolution, the breaker underwent rigorous manual and electrical charging. Additionally, the breaker resistant to leaving its case underwent a diagnostic, showing a connection fault to the racking mechanism. This was fixed and restored to its original state.
