Description

Technical Field

[0002] A current probe is a magnetic ring designed based on the Faraday principle to measure interference current signals in a conductor. It is essentially a transformer with one turn. Using a current probe, you can measure the current flowing through a conductor. The current flowing through a conductor causes an electromagnetic flux field to form around the conductor. The current probe is designed to sense the strength of this magnetic flux field and convert it into a corresponding voltage for measurement using an oscilloscope. This allows the current waveform to be viewed and analyzed using an oscilloscope. When used in conjunction with the voltage measurement function of an oscilloscope, the current probe also allows for various power measurements.
