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 NFPA 70B, with photographic reports; station battery and DC checks support the utility’s PRC-005 records.
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.
NFPA 70B · IEEE C2 (National Electrical Safety Code) · NERC PRC-005 (station DC supply checks)
Equipment types inspected.
Distribution and transmission substations, switchyards, plant substations, collector substations.
Deliverables from each job.
Every visit ends with a documented report: a photographic record, anomaly findings with severity ranking, photos, and a clear recommended-action list. Trends are tracked across visits.
