要約(英語): We proposed a new equation for predicting charge voltage for an insulated wire with a grounded core conductor placed under a DC transmission line. The equation was derived from the relationship between electric field and charge voltage on the surface of the insulated wire. The equation allows us to assess the charge voltage of an insulated wire in the steady state by using input parameters such as electric field and ion current density at the ground level. To validate the equation, the charge voltage at the outer surface of the insulated wire was measured using a surface potential electrometer under bipolar-DC test lines energized at 200 kV. The predicted results of the charge voltage agreed well with the measured results.
