Retrofit of Five PCB Transformers

A large equipment manufacturer contracted SUNPRO to replace five PCB transformers. The units were located on limited access mezzanines throughout the facility. SUNPRO performed direct replacement of four 1000 kVA units and upgraded one 750 kVA unit to 1000 kVA capacity. All replacement transformers were filled with R-Temp dielectric fluid. This turnkey project included: procurement of the replacement units, draining and removal of PCB fluids and carcasses, mechanical rigging of the new transformers, electrical disconnect and reconnect, transformer testing, PCB disposal, and transformer disposal.
