strømklemmer
Strømklemmer, often translated as "current clamps" or "clamp meters," are electrical testing instruments used to measure electrical current without direct contact with the conductor. They work by utilizing the principle of electromagnetic induction. A clamp meter has a jaw that can be opened and closed around a conductor, such as a wire or cable. When an alternating current (AC) flows through the conductor, it generates a magnetic field around it. The clamp meter's jaws contain a ferrite core that encircles the conductor, concentrating this magnetic field. A coil within the jaws then detects the changing magnetic field, and electronics inside the meter convert this signal into a current reading.
These devices are highly valuable for safety and convenience as they eliminate the need to break an
