It is inevitable. Electrical equipment will fail at some point if not properly maintained.

The benefits of a properly maintained electrical system include:

  • Employee and Public Safety
  • Increased reliability, efficiency and performance
  • Reduced insurance premiums
  • Avoidance of costly unplanned outages, replacement parts and repairs, lost productivity, and process interruption

Electrical Preventive Maintenance (EPM)

EPM involves the practice of conducting routine inspections, tests, and service in order to avoid equipment failures. A planned EPM program allows the owner to schedule system outages at a time of their choosing rather than having to respond to an untimely failure. Pre-scheduled service activities include:

  • Visual Inspection
  • Cleaning
  • Bus Tightening
  • Insulation Testing


Predictive Maintenance

Predictive maintenance is the practice of conducting diagnostic tests and inspections during normal equipment operations to detect weaknesses or impending failure. Non-invasive service activities include:

  • Electrical Load Monitoring
  • Infrared Thermography
  • Power Quality Analysis
  • Oil Sample Analysis
