電流互感器可將大電流值縮小為標準化的小值以供測量。它們提供的二次電流與其初級電路中流動的電流精確成比例。電流互感器對初級電路呈現可忽略的負載。

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.
