Abstract

A novel circuit breaker closing resistance instrument is designed in this paper. Super capacitor was used as test power source, and a digit signal processor as microcontroller, moreover AD526 and LM324 were used for signal amplifying and filtering. On-chip Analog-Digital converter was used to acquire voltage data. Closing resistance, loop resistance, and pre-insertion time can be measured in one closure using the instrument. Experiment results show the instrument´s high precision and high reliability. Besides, the instrument is very practical and easy to use in field.
