How Infrared Thermography Improves Electrical Safety and Reliability
Infrared thermography is a non-contact, non-destructive testing (NDT) method that allows inspection of equipment while in operation. It is a critical tool in modern predictive maintenance services UAE and condition monitoring services UAE, helping industries reduce downtime, prevent failures, and optimize maintenance strategies.
Case Study 1: Electrical Panel Hot Spot Detection (Before Failure)
Application
Medium Voltage / MCC Panel – Industrial Facility (UAE)
Problem Identified
Thermal imaging revealed a localized hot spot (≈ 110°C) at a cable termination due to a loose connection and high resistance.
Risk
- Potential electrical failure and fire hazard
- Risk of unexpected plant shutdown
Action Taken
- Immediate tightening and re-termination of the connection
- Load balancing verification
Result (After Correction)
- Temperature reduced to < 45°C
- Eliminated failure risk
- Improved system safety and reliability
Impact: Prevented a major failure and avoided costly downtime.
Case Study 2: Bearing Overheating in Pump (Mechanical Fault)
Application
