Substation Field Testing in Alabama
Southern Switch & Contacts sends field crews into Alabama for transformer testing, circuit breaker testing, acceptance testing, and routine substation maintenance. Alabama has a mix of Alabama Power transmission and distribution infrastructure, Tennessee Valley Authority (TVA) territory in the northern part of the state, and a large network of rural electric cooperatives serving distribution customers across the state's 67 counties.
The state's industrial load — including steel, automotive, and chemical manufacturing — puts a premium on transformer reliability. A maintenance testing program that catches LTC contact wear and insulation degradation before they become service interruptions protects those customers and the utilities serving them.
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.
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 Alabama — post-fault assessment and path to restoration.
We serve customers on Alabama Power's transmission and distribution system, TVA distributor utilities in northern Alabama, and cooperatives including Black Warrior Electric, Central Alabama Electric, Joe Wheeler EMC, Coosa Valley Electric, and others in the Alabama EMC network. Industrial transmission customers with dedicated substation infrastructure are also a significant part of our Alabama work.
Coverage areas include Birmingham, Mobile, Montgomery, Huntsville, Tuscaloosa, Decatur, and rural systems throughout North Alabama, the Black Belt, and the Gulf Coast region.
Tell us what you need tested, your outage window, and site location — we'll put together a scope and mobilization plan.
