Abstract :
This paper shows a new possibility for quality and reliability testing of low-current contacts by their non-linearity measurement. A common THD tester cannot be used for low impedance elements. Therefore, a special variant of the THD tester was developed. It was used for testing a set of relay contacts. The results of the tests proved the applicability of the proposed method.
