Infrared Thermography for Electrical Distribution Systems

Infrared Thermography For Electrical Distribution Systems Information about the conditions of electrical distribution systems gathered through Infrared Thermography is always correct and reliable. It is a determining factor in the supply of uninterrupted power to the consumers.  Ideally, whenever a fault occurs, you will have to switch off the supply, which might lead to dissatisfied customers and heavy financial losses.  On the other hand, infrared Thermography offers multiple advantages, including piecemeal inspection, quick identification of the defects, and diagnosing other components in their starting phase, preventing energy losses, short circuits, and expensive repairs. 

How does Thermography work?

Infrared scanning works through heat sensing, better known as ‘heat signatures,’ emitted from any surface or object in the form of radiation commonly referred to as infrared radiation.  To measure these infrared radiations in either temperature or value, various test instruments are used to find the object’s condition when they are measured. 

How can Thermography be used to inspect Electrical Distributions?

Electrical installations generate heat due to electrical resistance. This circulation of heat is directly related to the current in the electrical panels, elements, and connections within the entire power system.  When the conditions of the elements begin to deteriorate, their power of resistance also increases, resulting in high heat. Likewise, it will have a high resistance in a poor connection compared to a fully functional connection. 

Application of Thermography Infrared imaging professionals can detect the distribution elements in terms of heat patterns, faulty cables, broken wires, and other related problems to prevent electrical system failures. There are two categories of separate inspection, which are: Qualitative Inspection – In this case, you need to draw a pattern based comparison to temperature differences. This method is an excellent way to measure electrical distribution systems in a precise manner.

2. Quantitative Inspection – When there is a significant difference in temperatures, you can move on to quantitative inspection after considering several aspects, such as emission, wind speed, spatial resolution, optical resolution, and temperature.
