Starting with infrared thermography


Thermography interests• To save on the invoices of electricity by improving the output of the electric installations

• To locate the energy losses

• To avoid the stops of production, machine breakings

• To eliminate the fire hazards

• To decrease the insurance premium


Why thermography is it so useful ?

3 essential advantages:

•Non-contact measurement

•Method with two dimensions

•Real time method


Why use thermography?

•Better safe than sorry

That should be our motto!

•Infrared thermography: a powerful diagnostic tool for preventive maintenance

Enables corrective action to be taken prior to costly breakdowns


Thermography application

•Electrical maintenance

•Mechanical maintenance

•Building thermics

•Industrialisation/manufacturing

•Research and Development


Electrical maintenance


Thermography applications•Main use: electrical maintenance

•Objective:

Classification of faults in order of seriousness

Necessary to assess

•Recommandations



•Aim: highlight, in loaded electrical infrastructures, overheating due to:

Poor connections Material deterioration

Overloads Production stoppages

Phase unbalance Operating losses

Faulty contacts Fires …. ….



•Role of the camera:

Provide decisive elements enabling:

Identification of work to be undertaken

Facilitate maintenance, save time and increase safety



•Methodology

Scanning of the entire electrical installation when the elements are in normal load

Spatially located anomalies, possible calculation of overheating

Definition of extent of emergency and management of anomalies

measure of the quality of the contacts (switches, relay),

measure of the resistance and the resistivity of cables,

check of good mechanical connections,

measure of the resistance of the windings and\or the warm-up of motors and transformers,

...everywhere it is necessary to control the quality of the connections, the contacts and the surfaces.

INDUSTRIALISATION / MANUFACTURING:

Testing of instruments at end of chain, fast general checking, rejection of non-compliant assembly

Endurance tests on « heating table », detection on-the-spot and over time of proper functioning of parts

Endurance tests on « vibrating table », detection of faulty contacts, faulty joints, etc.

Testing of industrial processes

Paper industry

Industry: +120 °C to +900 °C

With high temperature filters (optional)


Research/development• Scientists researching new methods for solving

problems• Thermocouples:

- Have to be in contact with the component measured- Effect on the results

• Thermography:• Non-destructive analysis capacity• Detects very low differences in temperature,

highlights thermal exchange phenomena• No contact method, highlights the problem


Research/development

Heating of complex processors on printed circuits

Heating at the base of a component

Quality control during final phase of developmentProtection against short-circuits
