  1. Starting with infrared thermography

  2. 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

  3. Why thermography is it so useful ? 3 essential advantages: • Non-contact measurement • Method with two dimensions • Real time method

  4. 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

  5. Thermography application Electrical maintenance Mechanical maintenance Building thermics Industrialisation/manufacturing Research and Development

  6. Electrical maintenance

  7. Thermography applications • Main use: electrical maintenance • Objective: Classification of faults in order of seriousness Necessary to assess • Recommandations

  8. Electrical maintenance • Aim: highlight, in loaded electrical infrastructures, overheating due to: Poor connections Material deterioration Overloads Production stoppages Phase unbalance Operating losses Faulty contacts Fires …. ….

  9. Electrical maintenance • Role of the camera: Provide decisive elements enabling: Identification of work to be undertaken Facilitate maintenance, save time and increase safety

  10. Electrical maintenance • 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

  11. Faulty connection Faulty fuse contact Electrical maintenance BT/TBT electricity

  12. Fuse holder connection Cable head Electrical maintenance BT/TBT electricity Faulty connection

  13. Incorrect connection screwdown Electrical maintenance BT/TBT electricity

  14. CA 6250 : Micro-ohmmeter 10A • measure of continuity of the masses • measure of state of surface and plating, • 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.

  15. Wrongly calibrated fuse Electrical maintenance BT/TBT electricity

  16. CA 6115 : Electrical installations tester

  17. Electrical maintenance BT/TBT electricity Unbalanced load

  18. Power & Harmonics measurement CA 8230 Power & Energy Active Reactive Apparent Harmonics single / Balanced three-phase Série F0X F09 Clamp CA 8334 Power & Energy Harmonics single / three-phase Recordings Transient captures Trigerring on alarms… Power measurement Active Reactive Apparent TRMS

  19. Contact problem with selector Electrical maintenance HTA/HTB electricity Inspection of high voltage lines

  20. Faulty insulator Electrical maintenance HTA/HTB electricity Insulator support to be tested

  21. Faulty connection on high voltage connection Electrical maintenance HTA/HTB electricity Overheating on insulator connection

  22. Mechanical maintenance

  23. Mechanical maintenance • Because of friction, mechanical parts heat normally • Aim of thermography: highlight abnormal heating Replace parts in time

  24. Testing of mechanical heating Mechanical maintenance Faulty rotation

  25. Engine heating Mechanical maintenance

  26. Ventilator Mechanical maintenance Unbalanced thresholds

  27. Leaking valve Canalisation and insulation Blockage in a canalisation

  28. Deterioration of thermal insulation Canalisation and insulation Condition of thermal insulation to be inspected

  29. Paper industry Industry: +120 °C to +900 °C With high temperature filters (optional) 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

  30. 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

  31. Heating of complex processors on printed circuits Heating at the base of a component Research/development Quality control during final phase of development Protection against short-circuits

  32. OX7104 Portable oscilloscope 4 isolated channels Voltage, current, temperature measurement Recordings, Harmonics 12-bit converter Colour touch screen with graphic commands Ethernet communication MTX 3283 Multimeter Large display with up to 4x 100,000 counts V/A automatic selection via leads connection Recording and graphic processing up to 6,500 measurements Communication : Bluetooth or RS232 or USB

  33. Research/Development • Instruments for the general public Accelerate market launch Prior to production, comprehensive tests Ascertain usable power and the manner in which it is dissipated

  34. Research/Development • Automotive sector Solutions for thermal protection of engines Products for monitoring temperature beneath the chassis Instantly observe critical zones

  35. ResearchDevelopment • Pharmaceutical industry Observation of variations in temperature during chemical reaction, study on micro-plates

  36. Research/development • Food industry Development of new cooking/freezing techniques (techniques can be dangerous for public health)
