Thermography in electrical maintenance allows for more control and predictability over these scenarios so that shutdowns can be carefully planned for minimal impact. Thermographic testing can also indicate degradation of electrical insulation, showing areas where heat is escaping and where insulation must be replaced to remain safe.
Thermographic testing offers a host of advantages for manufacturers, especially as part of a comprehensive maintenance plan.
- Maintenance cost reduction
- Fast detection of temperature
- Increased equipment service life
- Improved safety
A hot spot is detected between the nut and rod on the LV bushing of the transformer in phase “B”. The Infrared camera detects effectively loose electrical connections in the bolt joint between the fixed live part, and the busbar on the upper and lower part of the current transformer on phase “B”
