変流器は、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。一次回路を流れる電流に正確に比例した二次電流を提供します。変流器は一次回路に対して無視できる負荷しか与えません。

The accuracy on these is spot-on—the secondary output stayed perfectly proportional even when I pushed 40+ amps through the primary. Compact enough to fit in my crowded panel, and the clamp locks securely without any wobble.
Been using this clamp to monitor my workshop's main feed and the secondary output is dead on compared to my multimeter readings. The 50A rating gives me plenty of headroom for the occasional spike, and the clamp opens wide enough to fit over thicker cables without a struggle.
Had to redo a couple of wiring runs in my panel, and this clamp made it trivial to verify the secondary current matches the primary exactly—the ratio held steady even under a heavy load. Fits nicely on the busbar without any awkward bending, and the terminal block feels solid for the price.
