Thermography - What it can do for you

Infrared thermography (thermal imaging) is a diagnostic tool to monitor and measure the radiant heat pattern emitted from a body, such as plant equipment or building structures. This technique can determine areas of heat emissions (hot spots) or temperature differences, which can indicate abnormal operation because of the presence of a fault in the equipment. The thermal imager basically captures and highlights any temperature anomalies in a system, which is a common indicator of a failing component or unevenly balanced electrical load or a leaking system.

Thermography is a technology that provides vital information for preventive maintenance over a wide array of applications. General groupings of the applications are as follows:

Electrical
Systems
Transformers, switchboards, earth faults, circulating currents, Laminations and high voltage overhead distribution lines
Mechanical
Systems
Pumps, motors, generators
Process
Systems
Piping infrastructure leakage
Air conditioning duct infrastructure leakage
Heat
Insulation
Systems
Storage tanks, boilers, steam systems tube, heat exchangers, temperature controlled room seal integrity(Lagging on pipework defective resulting in heat loss from motive fluid.) Refrigeration Systems

Applications

Electrical and Electronic Systems (Sboards, circuits, substations, transformers, UPS) Mechanical Equipment (Compressors, pumps, machine panels)
Piping Systems (Blockages/Leakages) Insulation (Buildings, tanks, storage containers)

Benefits and Advantages of Thermography

Our thermography services are vital for companies to reduce cost, save money and minimize downtime. Features are as follows.

  1. Thermography is a non-evasive and non-destructive technique (with the ability to inspect within walls and ceilings)
  2. Immediate indication and zooms in on the specific problem area
  3. Provides technicians with the exact location for troubleshooting
  4. Detailed analysis of results could be an early warning for any major fault and disruption
  5. The technical inspection and reports will enable companies to optimize its insurance premiums or rebates as thermography results provide a basis for risk mitigation
  6. Minimizing building hazard
  7. Minimizes energy losses in buildings

    Our Equipment

    Our equipment, made by Fluke, has a thermal sensitivity of ≤ 0.1 °C at 30 °C. A feature is IR-Fusion, a unique capability that captures a visible light image in addition to the infrared image. This means it takes a conventional photograph simultaneously with the infra red image so that the details in the picture are the same. This helps to better identify and report suspect components and enable the rectification to be made without trial and error methods. Combining both the infrared and visible light images helps the user identifies details to manage and analyze the images. The technology simultaneously captures pixel-for-pixel infrared and visible light images and allows full image optimization with 5 different on-camera as well as software viewing modes.

    Technical Expertise

    Technician:Our thermographic surveys are performed by Md Murtadza Bin Abdullah, originally trained by the Royal Malaysian Air force as an Air Electrical Technician. He has 32 years of electrical experience, ranging over aircraft, industrial and domestic electrical systems.

    Qualification: Md Murtadza Bin Abdullah is a certified Level I Thermographer. He is a qualified PW4 wireman and A1 chargeman, registered with the Energy Commission. Qualified to board offshore platforms - HUET (OPITO approved).

    Inspection Criteria:Our thermographic evaluations are based on the National Electrical Testing Specifications (NETA) for electrical equipment.

    Reporting: Our reports will highlight temperature exceptions based on NETA specifications and our own experience. Each exception will be given a priority rating. Exceptions that are considered to require immediate or urgent attention or indicate an unsafe condition will be brought to the attention of the responsible engineer before we leave the site.

    Supervision: Our thermographic inspection service is offered under the general supervision of our technical manager, Anthony Jarratt., who has more than 40 years industrial experience as an electrical engineer. Our full team includes mechanical, electrical, electronic, metallurgical and chemical engineers who can provide guidance in specialized areas.
