변류기는 측정 목적으로 큰 전류 값을 작고 표준화된 값으로 축소합니다. 1차 회로에 흐르는 전류에 정확히 비례하는 2차 전류를 제공합니다. 변류기는 1차 회로에 무시할 수 있는 부하를 제공합니다.

It’s so reassuring to see the secondary current stay proportional to the load like it should, and the clamp housing feels solid enough to leave in place for years. I checked it against my bench meter across a few loads and the scaling held up impressively well.
Ratios are dead-on across a range, and I love that the secondary output scales so cleanly with the primary load. Mounted it in my panel and the readings match my standalone meter within a few percent. Exactly what I needed for accurate energy logging.
The scaling is spot-on compared to my old meter, and the clamp fits snugly around my 100A feed. Hooked it up in five minutes, zero drift so far.
