Substation Inspections
A trained set of eyes through a substation every quarter catches what test equipment misses, oil leaks, corroded steel, broken arresters, missing labels, missing PPE in the control house. We run inspection rounds aligned with utility procedures and NERC PRC-005 requirements, with photographic reports.
What substation inspections cover.
- Visual inspection of yard apparatus and structures
- Oil and SF6 leak inspection
- Surge arrester and bushing condition checks
- Control house, batteries, and DC system walkdown
- Grounding, fencing, and signage verification
- Animal mitigation and vegetation assessment
- Photographic report with priority action list
Standards and protocols applied.
NERC PRC-005 (Protection System Maintenance) · IEEE C2 (National Electrical Safety Code) · NFPA 70B
Equipment types inspected.
Distribution and transmission substations, switchyards, plant substations, collector substations.
Deliverables from each job.
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.
