Description
Summary:Although the electric field due to high voltage power transmission lines has received considerable attention, relatively few papers have been published concerning fields prevalent in an HVdc switchyard. This paper reports measurements of electric field intensity conducted adjacent to and along a switch line in the Dorsey Converter Station of Manitoba Hydro at and above ground level. In addition, system data and weather information were also compiled. Because of the large volume of data collected, a database approach was used to analyze the results based upon chosen criteria. The magnitude of the electric field at the measurement locations has been computed using the Charge Simulation Method. Three models are considered, each incorporating different levels of refinement. The calculated values are then compared with the recorded maximum and overall average values.
