DHPC PDC 13.8KV Switchgear (Re-bid) HU 2026-49

This opportunity involves the detailed engineering design of a 115 kV medium‑voltage (MV) substation’s switchgear for the Don Henry Power Center. The scope covers the creation of schematics, wiring diagrams, relay logic, and auxiliary device integration for both the main breaker (52 MB) and feeder breaker (52 FB), as well as associated control building plans. The work is purely design‑centric, requiring close coordination with Hastings Utilities and adherence to the specified equipment (e.g., SEL‑751 relays, EMAX RAW‑1D coil‑monitor relays). • Produce complete schematic and terminal‑legend drawings for MV Switchgear Main Breaker (52 MB) and Feeder Breaker (52 FB). • Define and document relay I/O assignments, lock‑out relay logic, and wiring conventions for protective and auxiliary devices. • Deliver control building plans, mechanical detail of breaker contacts, and integration of CT/VT devices for the 115 kV substation.
