Development testing of the magnetically levitated train (MAGLEV) is well advanced in Japan. MAGLEV is unlike conventional railways, so various problems lie in the technology. One of them is surge analysis of the MAGLEV coil for propulsion and guidance (coil for propulsion). The coil for propulsion is installed on each side of the outdoor guideway. Thus, the power system of MAGLEV is always exposed to lightning and circuit switching. Accordingly, it is very important to do a rational insulation plan to prevent damage when surge enters the coils. In view of this situation the author performed experiments using the minimodel coils and clarified impulse voltage distribution at the end of each coil. The surge characteristics were simulated by giving the inverted L equivalent circuit to the coil for propulsion. As a result, the measured values and calculated values were almost equal in surge characteristics. Further, the surge characteristics of the Miyazaki test track and the future MAGLEV were examined. © 1997 Scripta Technica, Inc. Electr Eng Jpn. 118 (1): 71–82, 1997
