Benefits of Electrical Preventive Maintenance

Electrical failures can be inconvenient and costly. We utilize Infrared testing in our EMP process as it provides a non-destructive, time-efficient method of troubleshooting electrical faults. Here’s what to expect from our preventive maintenance program:

  • Fast, Accurate Diagnosis – use infrared scanners to detect hot spots that may not be visible to the naked eye or through traditional testing methods. This helps locate even the slightest problems, giving technicians a more effective way of diagnosing issues.
  • Minimizes Risks – troubleshoots components before replacing them, reducing the risk of malfunctioning or damaged parts.
  • Reduced Downtime – detects potential problems within a few minutes, eliminating the need for costly repairs or replacements.
  • Increased Energy Efficiency – detects poor connections and damaged components, which can lead to energy loss.
  • Improved Safety – identifies fire hazards, such as overloaded breakers, hot spots, high-resistance connections, and corroded electrical wirings.
