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.
- 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

Distribution and transmission substations, switchyards, plant substations, collector substations.
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.
