Abstract

In any quality improvement program, measurement system analysis (MSA) is a mandatory step to evaluate the entire process of obtaining measurements. This paper presents a case study on the analysis of a measurement system used to measure the resistance, ass a major characteristic of power transformers. MSA included evaluation of stability, linearity, bias, and repeatability and reproducibility (gauge R&R). Results showed that the measurement system could be accepted for the usage within six sigma project. Besides, the main source of the measurement variation has been detected, and a recommendation for the gauge improvement has been drawn.
