We work on a wide range of substation equipment—power transformers, breakers, switches, arresters, and control cabinets—and perform essential diagnostics such as TTR, winding resistance, insulation resistance, power‑factor testing, and oil analysis through our dedicated in‑house laboratory. The Field Service Supervisor provides senior technical leadership for complex transformer and high voltage apparatus projects, overseeing inspection, repair, maintenance, and testing of transmission and distribution substation equipment.
