Outline
:
Expressing power distribution in interconnected electric transmission system with many power stations and substations of different voltages by using matrix, it is shown that circle diagram of this system is given
the main'diagonal tegms of matrix as centers and the other terms as tadii., A humerical example is taken from the data of the main high ' tension transmission ,lipe of HolN'Z'vl・itYIt,t.2.... 2Y2 ',

of equivalent T circuits between

The equivalent n circuit bet-
