Abstract

PURPOSE:To detect DC current simply with a better performance by detecting an induced voltage of a generator depending on the magnetic field with the primary current after it is excited. CONSTITUTION:A small generator is excited as equipped with a rotary coil 8 which is rotated with a motor 9 in proportion to a DC current through a magnetic core 7a according to the DC current following through a primary conductor 1. As a result, an induced voltage is generated in the coil 8 corresponding to the direction in which the DC current flows in proportion thereto and detected with a DC voltmeter 12. This enables the detection of DC current in a better linearity with an excellent performance.
