“Fault Prediction in Electrical Equipments using Thermographic Inspection”

Abstract

Electrical power system deals with various new technologies, Also most part of electrical system in various industrial applications is automated. To maintain the reliability it is essential to carry out maintenance procedures. Temperature is one of the important parameter that should be taken into account in the maintenance, because higher temperatures indicate loss of energy in the form of heat. As temperature audits have much importance in the maintenance, now a day Thermo-graphic audits are carried out in many industries. Thermography is nothing but temperature profiling of a surface of electrical equipment. One of the major advantages of this type of technique is that this is contactless monitoring of electrical equipment without actually shutting down the equipment which gives reliable and fast prediction of faulty part of the system. In this paper image processing techniques are used for the analysis of thermal images of the faulty equipments. this paper deals with the study and analysis of Thermography as one of the fault prediction technique.
