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