| Abstract: | The measurement error caused by electrical potential connecting wire resistance and con-tacting resistance of Kelvin bridge was studied.Acomprehensive analysis for the error-in-ducing reasons was performed. The reasons were revealed which accounted for the differentmeasuring results when two kinds of fixture was used in cable D.C. resistance measure-ment.The effects of the current applied to the measurement system on the measuring resultswere also tested and the related errors were analyzed. |
