Fig. 149 Fig. 150 current in the middle wire will be equal to the current in the othertwo wires multiplied by ^2—that is, by 1.41. Fig. 151 illustrates thissystem ; a b are the two outer wires in the junction of the other two.In a continuous current system the pressure between the outerand inner… … Fig. 151 inner wire is 100 volts. That is not so with a two-phase three-wiresystem. If we add the pressures between the outer and inner wirethe sum will be greater than the pressure between the outers ; infact, it will be 1.4 times greater, so that if the outers differ in pres-sure by 100 volts,…
