It will be difficult to renew an auto transformer (AT) in Shinkansen long tunnel during maintenance time. We study a possibility to omit the AT from a viewpoint of rail potential and inductive interference on telecommunication line. When a test train ran, we measured rail potential and inductive voltage on telecommunication line in order to get fundamental data under two conditions. The one was normal status and the other was that an AT was disconnected. In addition, we calculated rail potential and inductive voltage, and we compared the calculated results with measured data. As a result, we found that it would be impossible to omit the AT because inductive voltage would exceed the restriction value.
