Crossing Type 3 Phase 2 Line Transmission Method Using Earth

다국어 초록 (Multilingual Abstract)

In the three phase two line transmis-sion method using earth, if we use several unit ratio transformers in series at ade quate intervals not only on a single circuit but also on two or three circuits constructed on the same towers, the constants (resistance and self-inductance) of the earth can be easily distributed even on the overhead lines. As the constants (resistances, self-inductances and static capacitances) of the overhead lines and the earth are equally distributed in each of the three phases, not only the balanced three phase currents flow through the earth, but also the three phase voltages can be balanced, consequently there are no the nearby located communication lines This new transmission method is just the same as the old three phase three line over head transmission method, conse quently we can use this new method every where.
