International comparison of standard systems for impulse current measurement

Authors


Abstract

The impulse current test is an important test that is used for the evaluation of lightning protection equipment. The quality of the test greatly depends on the measuring system. Some countries already have their own standard measuring systems. Standard systems are under construction in Japan and Korea. According to the international standard on high-voltage test techniques, a comparison test is needed to confirm the impulse parameters which have traceability or compatibility with the standard values. Different from intercomparison of impulse voltage measuring systems, Japan and Korea have not conducted an international comparison test for impulse current measuring systems. Now we have jointly conducted a comparison test for impulse current measurement. As a result, it was confirmed that the system of Japan is compatible with that of Korea, which is traceable to another foreign national standard.

In this paper, the result of the comparison test between two countries is described. © 2011 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
