Abstract

In this paper, The impulse un-tripping characteristics and the electro magnetic compatibility characteristics are compared with each other. The performance of impulse un-tripping test exists at domestic standard (KSC 4613). However test items are insufficient because the more test items such as EMC exist at international standard (IEC). Also, Electric Appliances Safety Certificate has taken the certificate test since July 2004 in Korea but did not confirm the EMC performance for RCCBs made in Korea. Thus, in this paper, We experiment with Oscillatory waves immunity test and the 7 EMC tests for 32 RCCBs of 4 types (mini, home standard, plug, outlet) for 16 brands according to IEC standard 61009-1 and 61008-1. As a result, 24 RCCBs proved to be poor for surge immunity test. However the RCCBs operating incorrectly for surge immunity test operate correctly for oscillatory waves immunity test. Thus, the correlation between oscillatory waves immunity test and EMC test is little and standard for compatibility of combination surge at IEC 61000-4-5 should be added to KS standard as soon as possible.
