Thermography is a test method used to detect poor connections, unbalanced loads, deteriorated insulation, or other potential problems in energized electrical components.
These problems may lead to excess power use, increased maintenance costs, or catastrophic equipment failure resulting in unscheduled service interruptions, equipment damage, or other problems.
Also known as infrared inspection, thermography relies upon sensing of the heat emitted from the surface of an object in the form of infrared radiation. To detect and convert the infrared radiation into either a temperature value or a thermal image, test instruments are used. These instruments are also used to assess the thermal condition of the object at the time of measurement. One of the most common types of infrared thermal imaging device is an infrared camera.
These cameras are used for inspections of various electrical and mechanical systems, pipework faults, refractory and petrochemical installations and components in all sizes and shape.
Some of the failures that can be detected with these cameras are:
- Oxidation of high voltage switches
- Overheated connections High resistance connections
- Corroded connections
- Internal fuse damage
- Internal fuse faults
- Poor connections and internal damage
- Incorrectly secured connections
- Insulator defects, poor connections in high voltage substations, switchgear, transformers, and outside circuit breakers
- Lubrication problems
- Overheated motors
- Suspect rollers
- Overloaded pumps
- Overheated motor axles
- Hot bearings
- Leakage in pumps, pipes and valves
- Insulation breakdowns
- Pipe blockage. refractory linings for furnaces, boilers, kilns, incinerators, kooky and reactors area unit at risk of degeneration and loss of performance, Flare detection, Tank level detection,
We use these methods and pieces of equipment to properly identify defects in the existing systems. After the identification, we begin the process to fix the faults.
