Mistakes that can be Made During Thermographic Measurements and How to Avoid them

Abstract

Thermal imaging or thermography is an extremely versatile measurement procedure. The user-friendly handling of modern thermal cameras is comparable to the widespread digital camcorders. In order to make thermal images that are accurate from the point of view of measurement, adequate theoretical, professional knowledge, experience and, in addition, measurement preparation are required. This article details the most important metrological requirements and practical knowledge of thermographic testing of electrical equipment. The effects of some common thermal camera operator errors, the accuracy and credibility of the measurements are also presented.
