【 摘 要 】

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.
