Substation Field Testing in Georgia
Southern Switch & Contacts deploys field crews throughout Georgia for transformer testing, circuit breaker testing, acceptance testing, and electrical maintenance on substation equipment. We serve Georgia's large utility fleet — investor-owned, cooperative, and municipal — from Atlanta metro substations to rural transmission and distribution stations across the state.
Georgia has a dense network of electric membership cooperatives operating distribution substations that range from aging equipment on original infrastructure to relatively recent additions. Many of the transformers in service across the state's co-op system are candidates for load tap changer maintenance, oil processing, and bushing assessment. We also support acceptance testing on new substation construction and protection system upgrades across the state.
DGA, Doble power factor (CHL/CH/CL), TTR, SFRA, winding resistance, bushing power factor and capacitance, insulation resistance, oil quality, and tap-changer maintenance.
Contact timing, contact resistance (micro-ohm), insulation power factor, minimum trip voltage, SF6 gas, and primary injection on medium- and high-voltage circuit breakers.
NETA ATS-compliant commissioning on new substations, transformer replacements, circuit breaker additions, and protection system upgrades.
Periodic maintenance test programs for transformers, breakers, instrument transformers, surge arresters, and protective relays across your substation fleet.
VLF withstand and tan delta for medium-voltage cable, TDR fault location, and pre-energization proof testing on direct-buried and duct bank cable runs.
Energized scanning of bus connections, cable terminations, transformer cooling systems, and switchgear to find hot spots before they become failures.
Station battery performance and service tests to IEEE 450, VRLA and flooded cell testing, charger verification, and NERC PRC-005 compliance documentation.
Rapid deployment for transformer failures, breaker events, and storm-related substation damage throughout Georgia — post-fault assessment and path to restoration.
We work with customers across Georgia Power's transmission and distribution system, Oglethorpe Power Corporation, the Georgia Transmission Corporation, and the network of Georgia EMCs — including Jackson EMC, Cobb EMC, Sawnee EMC, Greystone Power, Carroll EMC, Blue Ridge Mountain EMC, and others. Municipal systems in communities served by the Municipal Electric Authority of Georgia (MEAG) are also part of our service footprint.
Coverage areas include Atlanta metro, Savannah, Augusta, Columbus, Macon, Athens, Rome, and rural counties throughout North Georgia, Middle Georgia, and the coastal and southern regions of the state.
Tell us what you need tested, your outage window, and site location — we'll put together a scope and mobilization plan.
