Abstract (in Japanese) (See Japanese page) 
(in English) Electromagnetic induction between power and telecommunication lines has been studied since early 1900’s [1]-[5], because induced voltage may cause physical injury of service personnel, and malfunction or quality degradation of telecommunications． On the other hand, induction against suspension wires has been less studied because phenomena could be complicated so that it was connected to grounds at multiple points． In former study [6], Thevenin’s theorem was applied to a mesh circuit and calculated an induced voltage at one-side end． However, it couldn’t obtain voltage at each grounded points and calculation results depended on initial conditions of the circuit． In this paper, we have studied the induction phenomena against multiple point grounded conductor, theoretically and experimentally． First, we replaced induction model to equivalent mesh circuit and calculated voltages at each grounded point． Second, we have measured induced voltage at each grounded point by using 1/1000 scale model to confirm accuracy of the calculation model． Furthermore, since distance between connection points to the grounds and earthing resistances are vary in real situation, we have calculated voltages at each grounded point when those parameters varied at random．
