Abstract
A current-compensated current sensor for hysteresis-dependent and temperature-dependent measurement of even relatively large currents at different frequencies, includes a soft-magnetic magnet core having a flat magnetization loop. The sensor thus also permits rapid changes in a primary current to be measured.
