要約(英語): Objects or human bodies under DC overhead transmission lines may be charged with ion flow due to corona discharge generated on the surface of charged conductors. Ion flow electrification is an important considerations in the construction and operation of DC overhead transmission lines, and the charged voltage due to ion flow is the item that determines the height of DC overhead transmission lines. In order to clarify the electrical environment around 200kV DC overhead transmission lines, ion flow verification tests were conducted using test lines at the Shiobara Testing Yard of CRIEPI. In this paper, the ion flow phenomenon of 200kV DC transmission line are clarified. The measurement results are shown of the current of corona discharge flowing in test lines, the ion flow charging voltage and of the surface ion current density under test lines.
