description PURPOSE:To detect DC high current precisely in an insulated state by shunting a main circuit current almost evenly into >=2 circuits and detecting the shunted current with a miniaturized current detector. CONSTITUTION:Current ID flowing in a main circuit conductor 2 is shunted into 3 shunt conductors 5, 5', 5'' and current flowing in these shunt conductors is detected by current detectors 1, 1', 1''. When the output resistances R1, R2, R3 of current detectors 1, 1', 1'' are connected in series, the output ED becomes the sum of the output voltage ED1, ED2 ED3 of each current detector and is proportional to current ID. In these condition, the size and material of shunt conductors are equalized so that the current from the main circuit flows into each shunt circuit conductor almost evenly and I1=I2=I3 is formed. Thus, DC high current can be measured by an inexpensive and simple device.
