MV Class Intercomparison Tests for Impulse Measuring systems in Japan

Abstract

A research committee organized in the Institute of Electrical Engineers of Japan (IEEJ) carried out a series of intercomparison tests using a lightning impulse voltage measuring system which was developed by another research committee as one of the Japanese national standards. This project was performed as a final technical check to establish an accreditation system for measuring lightning impulse voltages in Japan. Ten organizations participated, of which eight were manufacturers, implying that the tests were very realistic and practical. The tests ensured the prospects of establishing the accreditation system.
