Substations

Structured, predictive maintenance to keep core infrastructure stable and safe

• Sandhills performs comprehensive testing, calibration, and servicing of all substation components.
• Maintenance includes breaker testing, voltage regulation, relay diagnostics, and transformer monitoring.
• Seasonal and weather-aware system checks prepare our substations for shifting grid demands.
• We conduct predictive analyses (e.g., dissolved gas and oil assessments) to prevent failure and extend asset life.
• Grounding systems and backup power are tested routinely to ensure uninterrupted grid support.
