電流トランスは、測定目的のために大きな電流値を小さな標準化された値に変換します。一次回路に流れる電流に正確に比例した二次電流を提供します。電流トランスは一次回路に対して無視できるほどの負荷しか与えません。

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.
