Thermographic testing is a non-destructive test method that may be 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.
THERMOGRAPHIC TESTING OF ELECTRICAL EQUIPMENT
A useful addition to a preventative maintenance program, Carelabs can carry out a thermographic scan and Thermographic Testing of all areas likely to be running too hot or too cold. The number one application for infrared thermography globally is electrical applications. 80% of electrical faults are not visible. Thermal imaging is the technique for making invisible infrared radiation visible. Thermal images capture fully radiometric infrared images using IR-Fusion® technology, photographic images and will be included in a report.
HOW DOES THERMOGRAPHY WORK
Thermography, also called infrared inspection, is based upon the sensing of heat emitted from the surface of an object in the form of infrared radiation. Test instruments are used to detect and convert the infrared radiation into either a temperature value or a thermal image, which can be used to assess the thermal condition of the object at the time of measurement. An infrared camera is one common type of an infrared thermal imaging device.
WHAT THERMOGRAPHIC TESTING SURVEY CAN IDENTIFY?
Thermographic surveys use infra-red cameras to identify ‘hot-spots’ on switch gear and low voltage equipment.
It can identify :-
Carelabs carries out surveys on switchgear, control panels, transformers, motors and controls and all accessible items of distribution equipment using infrared imaging to detect and locate faults which could lead to system failure and / or the initiation of any hazards and / or fire.
Through thermal imaging Carelabs Engineers identify electrical or mechanical equipment with hotspots due to the following:
♦ Loose breaker terminals
♦ Overload circuit breakers
♦ Overheated cables due to excessive load
♦ Poor cable insulation
♦ Arcing faults
♦ Motor’s low-level oil
♦ Overheated motors
Our teams are qualified and licensed to carry out Thermographic Survey.
