Abstract
This paper shows a new possibility for quality and reliability testing of low-current contacts by nonlinearity measuring. A normal third harmonic distortion (THD) tester cannot be used for low-impedance elements. Therefore, a special variant of the THD tester is described for this aim. This method was proved at a set of relay contacts and the results of testing validate a propriety of proposed method.
