CONDITION MONITORING OF ELECTRICAL EQUIPMENT USING THERMAL IMAGE PROCESSING

Abstract

This is an Infrared thermography or thermal imaging which is a very convenient and non contact method which has been used for many types of physical asset such as electronic component, buildings surveys, and mechanical components and equipments. Excessive temperature rise will result into the majority of failures in electrical equipments. The condition monitoring plays an important role for identify the faults. This Infrared thermography was first used for military application but now a days cost effective , reliable and non contact type infrared thermographic system is being utilized in this identification as well as for fault diagnose .This paper presents a survey on different thermal imaging techniques for fault detection and diagnose based on the object temperature. In this paper, thermal images of some electrical equipments have been taken and converted into HSI colour model for the further processing unlike other techniques, instead of grey scale images, hue region has been taken into consideration and then different gradient based on the edge detection like Prewitt, Roberts and Sobel are used to find the hot region of the thermal images.
