Abstract

The optical contact-loss measuring system based on the detection of arcing photons uses visible rays in measurement, which is executed only at night because the method's accuracy is reduced by environmental light. This problem can be solved by adopting a new system based on the detection of ultraviolet rays, which is expected to be adopted by The International Electrotechnical Commission in the future. However, the new system has the drawback of being very expensive. This paper reports on a low-priced measurement system developed to address the issue.
