Emergency Response
When a substation goes down, the right phone call gets you a real engineer — not a queue. Southern Switch & Contacts maintains 24/7 availability for utility emergencies, with same-day or next-day field dispatch depending on crew availability and travel distance. We carry the contacts, the test equipment, and the in-house machining capability to make parts on the fly when an OEM is no longer an option.
- Phone triage with a Southern Switch engineer
- Remote review of trip records, relay events, photos
- Field dispatch — crews mobilized from Palm Harbor, FL
- On-site assessment, isolation, and switching support
- Temporary repairs and reverse-engineered replacement parts when discontinued
- Post-event documentation and follow-up rebuild scope
NFPA 70E (electrical safety in the workplace) · IEEE C2 (National Electrical Safety Code) · utility-specific lockout / tagout and switching procedures
Substation transformers, oil & vacuum circuit breakers, switchgear, voltage regulators, reclosers, disconnect switches, and the controls/relays that go with them.
Every visit ends with a documented report: raw test data, calibrated instrument records, anomaly findings with severity ranking, photos, and a clear recommended-action list. Trends are tracked across visits.
Send a scope or a list of assets and we’ll respond within one business day with crew availability and a proposal.
Documented acceptance tests on new substation equipment before energization.
NFPA 70B and IEEE-aligned periodic testing to keep substation equipment in service.
DGA, oil quality analysis, TTR, Doble power factor, and SFRA on power transformers.
Contact resistance, timing, HiPot, and primary injection on oil, vacuum, and air breakers.
VLF tan delta, partial discharge, insulation resistance, and HiPot on medium-voltage cable.
Thermographic surveys of energized substations with documented anomaly reports.
IEEE 450 / 1188 testing on station batteries, chargers, and DC distribution.
Routine and detailed walkdowns — safety, asset condition, NERC PRC-005 readiness.
