PROJECT OVERVIEW
ITI supplied a 25kV MV lineup with outdoor step-down transformers and a 3,000A main-tie-main LV switchboard. The system was integrated for continuous duty on an accelerated schedule. To meet grounded neutral requirements on a multi-source lineup, ITI engineered and implemented a specialized Modified Differential Ground Fault (MDGF) protection scheme that delivers selective, CSA and UL compliant fault clearing while maintaining service continuity. The result is reliable power for bus charging infrastructure, reducing downtime and supporting a cleaner electric fleet.
