Proactively Uncover Hidden Risks

Predictive Electrical Maintenance

Infrared thermography

This non-invasive method detects heat anomalies like loose connections, overloaded circuits, and insulation failures—helping prevent equipment damage, costly downtime, and electrical fires.

ultrasonic Testing

This service complements infrared imaging by detecting inaudible sound waves caused by corona, tracking, and arcing—helping identify failures in components like switchgear and transformers to prevent unplanned shutdowns.

voltage & current analysis

C&H Electric analyzes voltage and current to detect issues like drops, distortion, or imbalances—protecting equipment and ensuring stable, safe power distribution.

visual inspection

Visual inspections catch wear, damage, or code issues early—helping prevent downtime, safety risks, and compliance violations.

Aerospace & Defense Manufacturer
Predictive Maintenance
$300K Downtime Prevented

Aerospace & Defense Manufacturer — East Hartford, CT

Infrared Thermography Prevents Production Shutdown

<$10K investment → $300K loss avoided

During a scheduled infrared scan at an active aerospace manufacturing facility, C&H technicians detected a failing circuit breaker feeding a main bus duct — actively melting insulation. Left undetected, the failure would have shut down all production for 3–4 weeks at $2,500/hr. The issue was corrected before any failure occurred.
