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.

본 논문은 누전차단기의 충격파 부동작 특성과 전자기적합성(EMC) 특성비교에 관한 것이다 국내 규격에서는 충격파 부동작 성능만 확인하지만 국제규격에서는 많은 EMC 항목이 있다. 누전차단기 17종에 대하여 EMC 4항목을 실시한 결과, IEC 61000-4-5에 따른 조합서지 내성에서 9종이 불량이었다. 다른 항목에서는 불량이 발생하지 않았다. 오동작만 발생한 시료 2종에 대하여 충격파 부동작 성능을 평가한 결과 오동작이 발생하지 않았다. 이것으로 보아 EMC와 충격파 부동작 시험은 상관관계가 적으며 보완이 필요함을 알 수 있다.
