Infrared Thermography Inspection – Eletrical Systems
Electrical systems are the most critical items within office buildings and industrial applications. There are considerable benefits to be gained by protecting these systems and reducing unplanned stoppages. Thermography is ideal for carrying out Electrical Safety Inspections, be it to source that loose bus-bar connection or that overloaded component in your main electrical panel.
Low Voltage Inspections
Electrical cabinets and motor control centers are regularly scanned with a thermal imaging camera. If left unchecked, heat can rise to a point that connections melt and breakdown; as result, fires may break out.
Examples of failures in low voltage equipment:
- Poor connections and internal damage
- Internal circuit breaker faults
- High resistance connections
- Corroded connections
- Internal fuse damage
High Voltage Inspections
Heat is an important factor in High Voltage equipment. When electrical current passes through a resistive element, it generates heat. An increased resistance results in an increase in heat. Temperatures of the cooling fins and the high voltage connection can be compared so that, if necessary, corrective action can be taken before real problems occur. Other high voltage installations that are checked with an IR camera include Circuit Breakers and Switchers and High-Voltage Power Lines.
Examples of failures in high-voltage installations:
- Oxidation of high voltage switches
- Incorrectly secured connections
- Overheated connections
- Insulator defects
