THE CONSTRUCTIONS OF ELECTROMAGNETIC TRANSDUCER OF UNBALANCE OF THREE PHASES CURRENT

In the paper given the materials of construction of electromagnetic transducer of asymmetry of the three-phase current to a voltage (EMPNSTN) based on magnetic circuit made in the form of oppositely disposed two symmetrical parts, each of which along the magnetic axis are three semi-circular recesses forming the round holes for arranging the phase conductors of three-phase mains, and four air gaps between the holes are four flat measuring coil on the insulating product lines, with the number of turns of the two outermost flat measuring coils is two times less than the number of turns of the two secondary flat measuring coils, and on the projections of the two ends of the yoke provided with holes for arrangement screws with nuts of a nonmagnetic material allowing to expand the functionality of the device of control unbalance in electric nets of communication objects.
