전자 장비에 대한 공기 방전 내성 테스트는 온도(T) 섭씨 15~35도, 상대습도(RH) 30~60%. 이는 공기 방전 테스트가 넓은 기후 범위로 인해 상당히 다른 테스트 결과를 제공할 가능성이 있음을 의미합니다. 공기 방전 테스트에 대한 위의 기후 조건의 영향을 명확히 하기 위해 이전에 2가지 조합에서 15mm/s의 접근 속도에서 80kV~6kV의 테스트 전압을 사용하여 정전기 방전(ESD) 발생기의 공기 방전 전류를 측정했습니다. T IEC 지정 범위 및 지정되지 않은 기후 범위의 RH. 그 결과, 다음과 같이 결정되는 절대습도(AH)가 동일한 것으로 나타났습니다. T 및 RH는 서로 다르지만 방전 전류의 거의 동일한 파형을 제공합니다. T 및 RH, 그리고 더 높은 테스트 전압에서 전류 피크는 AH가 증가함에 따라 감소합니다. 본 연구에서는 공기 방전이 테스트 전압에 미치는 복합적인 영향을 추가로 조사합니다. T, RH 및 AH는 20mm/s 및 80mm/s의 두 가지 서로 다른 접근 속도에 대한 것입니다. 그 결과, 80mm/s의 접근 속도는 동일한 기후 조건에서 이전과 동일한 결과를 제공하는 것으로 확인되었으며, IEC 규정 기후 조건에서 15kV의 테스트 전압에서는 30% RH 이상, 20mm/s 접근 속도는 동일한 AH에도 불구하고 80mm/s의 전류 파형과 완전히 다른 전류 파형을 생성하며 피크는 기본적으로 AH의 영향을 받지 않습니다. 그러나 RH가 20% 미만인 IEC의 지정되지 않은 기후 조건에서는 AH가 증가함에 따라 더 높은 테스트 전압에서 피크가 감소합니다. 이러한 결과는 동일한 AH 조건에서 80mm/s에서는 공기 방전 피크가 RH의 영향을 거의 받지 않는 반면, 20mm/s에서는 RH가 낮을수록 공기 방전 전류의 피크가 더 높다는 것을 의미합니다.

Abstract: Air discharge immunity testing for electronic equipment is specified in the standard 61000-4-2 of the International Eelectrotechnical Commission (IEC) under the climatic conditions of temperature (T) from 15 to 35 degrees Celsius and relative humidity (RH) from 30 to 60%. This implies that the air discharge testing is likely to provide significantly different test results due to the wide climatic range. To clarify effects of the above climatic conditions on air discharge testing, we previously measured air discharge currents from an electrostatic discharge (ESD) generator with test voltages from 2kV to 15kV at an approach speed of 80mm/s under 6 combinations of T and RH in the IEC specified range and non-specified climatic range. The result showed that the same absolute humidity (AH), which is determined by T and RH, provides almost the identical waveforms of the discharge currents despite different T and RH, and also that the current peaks at higher test voltages decrease as the AH increases. In this study, we further examine the combined effects of air discharges on test voltages, T, RH and AH with respect to two different approach speeds of 20mm/s and 80mm/s. As a result, the approach speed of 80mm/s is confirmed to provide the same results as the previous ones under the identical climatic conditions, whereas at a test voltage of 15kV under the IEC specified climatic conditions over 30% RH, the 20mm/s approach speed yields current waveforms entirely different from those at 80mm/s despite the same AH, and the peaks are basically unaffected by the AH. Under the IEC non-specified climatic conditions with RH less than 20%, however, the peaks decrease at higher test voltages as the AH increases. These findings obtained imply that under the same AH condition, at 80mm/s the air discharge peak is not almost affected by the RH, while at 20mm/s the lower the RH is, the higher is the peak on air discharge current.
