변류기는 큰 전류 값을 측정 목적에 맞게 작고 표준화된 값으로 변환합니다. 1차 회로에 흐르는 전류에 정확히 비례하는 2차 전류를 제공하며, 변류기는 1차 회로에 무시할 수 있을 정도의 부하를 줍니다.

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.
