Control of Cable Insulation Quality by Changing of Electrical Capacitance Per Unit During High Voltage Testing

摘要

Abstract. The paper describes the complex method of insulation quality control. It was found that electrical contact between bead chain electrodes and insulation surface can be provided by surface discharges along the entire length of the controlled zone. The pattern of electromagnetic field was developed by using Comsol Myltiphysics software. 1. Introduction One of the parameters, which have high influence on the operational characteristics of the cable product, is a quality of the insulatio.
