Abstract
A current measuring apparatus for polyphase current wherein reverse poled parallel diodes in each of the polyphase lines provide separate direct current paths for the alternate half cycles of the polyphase current. Alternate half cycles having like polarity of each phase are summed using the magnetic field created by the current components and a Hall-effect device.
