要約(日本語): In order to meet the increasing demand for electric power, underground cables of two or more circuits are installed in ducts in parallel for several kilometer in the same route. It, however, has not been known generally that the sheath circulating current is generated in a system where a large number of cables are laid on the same route.
Therefore, the sheath circulating currents were measured for this study in an actual power system of underground cables, and are analyzed by a generalized circuit analysis program EMTP for comparison with the measured vales, It is proved that sheath circulating currents generated in unbalanced horizontal arrangement and length can be analyzed well by EMTP.
