Electrical Systems :

To ensure the integrity of electrical installations for reduced down time, fire and

safety, or assurance company compliance, we highly recommend performingInfrared Thermal Imaging of electrical installations to find overheating in

connections and components, or faulty components. General inspection areas

are:

Electrical inspect ions in buildings, plants, facilities, refineries.

Overhead urban and rural distribution electrical inspections

Substation Electrical inspections, transformers and capacitor evaluation

Pow er generation generator inspections. Circuit board, Distribution board and Main Sw itchboard inspections

Pow er distribution units

60-70% of fire claims can be linked to electrical issues.

Mechanical Systems:

Infrared Thermal Imaging of motors, pumps, fans, bearings, compressors,

heating elements, humidifiers etc. can be analyzed for faults and decrease in

efficiency. Fatigue and stress concentration in components can be detected

and verified. General inspection areas are:

Electrical motor inspections, mechanical bearing inspections

Pow er Plant boiler flue gas leak detection

Refinery process line insulation loss or leak detection Refinery process evaluation

Heat exchanger quality and efficiency evaluation

Furnace refractory (insulation) inspections

Furnace Internal flame evaluation and tube inspections

Flame propagation explosion analysis.6

Buildings and Processing Equipment:

Internal properties in walls and pipes such as building and cool room/oven

insulation and efficiency, scale build up, fluid build up in composite

structures etc. can be determined. General inspection areas are:

Thermal heat loss inspections for buildings, plants, facilities, refineries.

Moisture contamination evaluat ions in buildings, condo's, plant

facilities

Concrete integrity inspections

Concrete Water Heated floor inspections for leaks and temperature

distribution

Flat roof leak detection for buildings, plants, facilities

Cold Storage cooling losses.

Heat ventilation air conditioning equipment evaluation 7

Energy:Identification of energy issues for rectification. Thermal Imaging is an integral

part of Energy Audits. Report is an addition to existing energy audit reports.

UK Government promotes technology for practical energy auditing.

General Inspection areas are:

Thermal heat loss inspections for buildings, plants, facilities, refineries. Moisture contamination evaluations in buildings

Insulation effectiveness and verification

Room temperature verification

Refrigeration and airconditioning

Lighting temperature performance

Energy loss from pipe work

HOT FUSE CLIP

Visible Light Image Infrared Thermal Image

This B phase fuse clip appears to be loose or corroded. These spring clips startto soften and lose their tension at 200. The connection then becomes loose

and allows dirt to enter and then the corrosion starts.Corrosion builds resistance and resistance builds heat.

WIRE CONNECTION


Here we see that even the smaller wire connections can cause potentialproblems.

This control wire connection is loose and if it fails ,the machine that itcontrols is shut down.

11


12/40

SWITCHING AND FUSES ABOVE TRANSFORMERS


These crimped connections between these transformers appear to be loose.

They should be checked. A failure here would shut down the entire system.

ELECTRIC MOTORS

Notice the hest in the inboard bearing. Normally the bearings should be coolerthan the jacket of the motor. The centre of the motor is where the very slighttolerances are from the rotor bars and the stator turning. It should be hotter inthe middle of the motor and not on the ends. This bearing is most likely in thefirst or early second stage of failure. The grease will break down and startleaking out and the bearing will eventually fail.

17/40

HOT MOTORS


This motor is running too hot. Most motors are rated at 40C (104F) overambient for a maximum heat rise. Once a motor reaches that maximum for anylength of time, the life expectancy of the motor is cut in half. For every 10

above that maximum heat rise, the life expectancy is cut in half again. Heatcould take a 20 year motor and turn it into a 5 year motor pretty fast. Thismotor is probably overloaded or over greased.

FLAT ROOF LEAK DETECTIONVisible Light Image Infrared Thermal Image

Interior infrared survey conducted during daytime hours reveals central area

saturated with moisture and in need of immediate repair.

MOISTURE CONTAMINATION


The thermogram of this vinyl-sided 3-floor apartment house clearly shows the pathof a serious leak from a washing machine on the third floor, which is completely

hidden within the wall.

21/40

PARTIALLY BLOCKED DRAIN PIPES


Image shows pipes becoming blocked. Further build up has likelihood of a

serious blockage and consequent damage.

WATER LEAKS


Water logged cool room insulation.

22


23/40

STRUCTURAL STEEL


This is usually where the bars are joined in a bolted splice. Over time theexpansion and contraction from heating and cooling along with vibration from theplants daily routines, will cause the bolts to become loose. There is no way to seethis without Infrared Thermal Imaging. This was done from the floor, withoutclimbing up and opening the boxes.

24/40

CONCRETE DETERIORATION


Note the de-bonded concrete layer on viaduct parapet wall. Thethermographic image has made it possible to efficiently and accurately detectthe precise development of loosening or cracking concrete that can lead to

concrete exfoliation in future. The safeguarding of third parties againstpotential disasters is dramatically improved through thermal imaging.

24


25/40

PROCESSING


Here we used Infrared Thermal Imaging to see the level of liquid in the tank.The vapour space above the liquid is warmer than the liquid and thus we seethe temperature differential. The liquid will have a higher thermal capacitance

(ability to store energy) than the vapour space, and that is why we can see thedifference.
