Data record `instr.clamp-meter.current-transformer-jaw`

Verified 2026-10-27 Confidence: High

In a current-transformer clamp the iron jaws form a magnetic core with the measured conductor as a single-turn primary and a coil wound on the jaws as the secondary; the secondary current is a fixed fraction of the conductor current set by the turns ratio, and the method responds to alternating current only.
