Question 133Electricity & Electronics - Assistant Engineer

The correct answer is C) heat sensitive thermography. Heat sensitive thermography, also known as infrared thermography, is a testing technology used to detect potentially dangerous loose or corroded bus bar and controller connections. This non-invasive technique uses a special camera to detect and visually display any areas of elevated temperature, which can indicate issues with electrical connections and components. This allows for periodic monitoring and early detection of problems before they become critical. The other answer options are incorrect as they do not accurately describe the testing technology being referenced. Corrosion electrolysis, electric vibroanalysis, and visual pyrotronics are not the appropriate terms for this type of electrical system inspection.
