This paper explores how the installation of the full-view micro-sensor detector will affect the electric-field distribution of ±800-kV converter valve. We build the 3D model of ±800-kV converter valve tower and use Ansoft Maxwell 3D Field Simulator to study the electric-field distribution of ±800-kV converter valve tower with the full-view micro-sensor detector at different logical suitable locations. The results show that the installed locations have nearly no influence on the maximum electric-field distribution of non-direct contacted components; but for the direct-contacted components, the maximum electric-field has increased to a certain degree. The results further show that the electric-fields distribution especially the maximum electric-fields distribution at different locations is different, but the maximum electric-field value is still less than the 3 kV/mm. Thus, it can be concluded that the installation of full-view micro-sensor detectors can lead to an increase of maximum electric-field, but it has no influence on the insulation condition of valve tower, and the insulation design still meets the requirements well. Finally, the experiment validates that the installation of the full-view micro-sensor detector is feasible.
