What is electrical thermography test?
Thermography is a non-destructive test method that may be used to detect poor electrical connections, unbalanced loads,deteriorated insulation, or other potential problems in energized electrical components.
In Thermography, the heat signature of an equipment is captured by Infra Red imaging. This enables visual indication of hot spots which are not visible to the naked eye.
- NFPA 70 B standards recommends thermography to be done as a critical part of Electrical Preventive maintenance Program and prescribes that thermography should be done annually.
- Thermography enables service/installer/maintenance technicians to AVOID fighting fires and fix problems before they result in large-scale losses.
- Excessive heat can result in Equipment Failure and Damage, Fire Accidents, Safety Threats to humans, Burns & injuries. Hence it is recommended to conduct Thermography Tests periodically as a proactive measure.
Possible Causes Excessive Heat:
- Worn Out, Loose, Wrong and High Resistance Connections
- Unbalanced and Over Loads
- Component malfunction and failure
- Improper Cooling
- Harmonic currents
- Misalignment of Equipment
- Insulation Failure
- Bearing – Excessive Wear and Inadequate Lubrication
