摘要：A current sensor for measuring an electric current flowing through a currentbus bar includes: a magnetic core with an opening, through which the current bus barpasses with a predetermined interval; and a first magnetic sensor for detecting magneticflux density in the magnetic core, the magnetic flux density generated by the electric
current passing through the current bas bar. The magnetic core has a first gap and asecond gap. The first magnetic sensor is disposed in the first gap. The second gap iscapable of preventing magnetic saturation of the magnetic core.
