| Abstract: | The harmful effects on communication cable from electricity line is an important problem in engineering.The authors give a method of estimating the currents that appear in the coatxial inner conductors and the voltages that arise between coaxial inner and outer con- ductors.An exact expression of the induced currents and voltages caused by the contact line of AC electric railway supplied with both two near traction substations is offered,and the distributions of currents and voltages in the coaxial inner-to-outer-conductor circuit are shown in some cases. |
