<li>누설전류 센서란?<br />
<ol><br />
<li>누설전류 센서란, 3상 또는 2상을 동시에 통과시킬 때(또는 접지선만 측정할 때) 누설되는 전류를 측정할 수 있도록(즉 매우 낮은 전류) 감도가 높은 재료를 사용한 클램프 센서를 말한다.<br />
<li>물론 AC 전류 또한 측정할 수 있다.<br />
<li>이런 높은 감도를 위해 high-permeability magnetic material of the sensor's core 와 magnetic shield 기술을 사용했다.<br />
</ol><br />
<li>Hioki PQ시리즈 파워미터용<br />
<ol><br />
<li>범용, Hioki, 9657-10, AC 10A, 출력 100mV/A, 코어 jaw 직경 40mm<br />
<li>Branch circuit용, Hioki, 9675, AC 10A, 출력 100mV/A, 코어 jaw 직경 30mm<br />
</ol><br />
<li>Hioki PQ시리즈 파워미터용(두 파워미터 시리즈에 따라 왜 다른 누설전류 센서를 사용하는지 모르겠다. 센서 출력은 모두 단순 BNC단자이므로)<br />
