Thermography Audit of Electrical Installations

A Sample Thermography Scan

Thermography Audit of Electrical Installations is an important aid for Electrical Maintenance Engineers to implement preventive maintenance schedules. The image to the left is a thermography scan of an MCB in a small distribution board. We can clearly see that the Y phase terminal has a brigher color indicating overheating due to loose connection of the cable connection.

Maintenance Engineers all know from bitter experience that  maintenance is a thankless job. Breakdown maintenance, in particular, is not only a thankless job but also nightmarish and a tension filled experience. To break out of the recurrent cycle of repeated breakdown maintenance, it is essential to rigorously implement a well planned preventive maintenance schedule.

For Electrical Maintenance Engineers, a vital part of the  preventive maintenance schedule is accurate and timely pinpointing of loose connections, overloading and hot spots in the electrical circuits. This is a tedious process with the added constraints of repeatedly arranging shutdowns of loaded equipment and panels to access electrical terminations and joints. This is where modern technology comes to the rescue.

Thermography, which involves the use of infra-red cameras to scan a heat source, has been in use in various fields including medicine and defence. Specialized thermal imaging cameras calibrated to scan electrical installations are now available to Electrical Engineers to assist in maintenance of electrical installations. Without prolonged shutdowns, it is now possible to scan live electrical systems to detect hot spots caused by overloading, flash-overs and loose connections and take preventive action before breakdown occurs.


Professional establishments are gradually including thermography as part of their preventive maintenance schedules.  Please contact me for more details about how you can use thermography as part of your preventive maintenance.

Chartered Engineer Certificate For Export Of Defective Parts/Equipments For Repair & Return


M/s WXYZ had imported a Laser Beam Projector, from a supplier in Germany, in 2011 for use as part of lighting and special effects systems in dance shows. In the course of usage, this laser beam projector developed some defect and needed to be repaired. M/s WXYZ made enquiries and came to know that this equipment cannot be repaired in India and needed to be sent back to the OEM ( Original Equipment Manufacturer ) for repairs. They coordinated with the OEM and made arrangements for sending the equipment to Germany for repairs. However, the Courier rightly refused to pickup the equipment for delivery based on the available documentation and insisted on a certificate from a chartered engineer. M/s WXYZ approached me for a certificate and the certificate was issued after inspecting the equipment and based on scrutiny of the required documents. With this certificate, M/s WXYZ were able to send the equipment for repairs and re-import the repaired equipment.

If you have an imported equipment/ machinery/ instrument which needs to be sent abroad for repairs, you will need to follow the same procedure. Customs Authorities have put this procedure in place to ensure that items which are exported for repairs and then re-imported after repairs are not subject to levy of customs duties. In the absence of a chartered engineer certificate, at the time of re-import after repairs, the customs authorities may levy customs duties as applicable on import of a new equipment.

To get this certification, the damaged/defective item has to be inspected by the chartered engineer. A couple of documents also need to be verified by the chartered engineer. These include the purchase invoice and bill of entry for import of this equipment. Based on these, the chartered engineer will issue the required certificate in the prescribed format.

If you require this certificate in or around Bangalore, please contact me.
