Characteristics of electrostatic discharges between metallic objects in the ion-flow field under HVDC lines

open access: yesThe Journal of Engineering, 2019
Metallic objects under high-voltage direct current (HVDC) transmission lines will produce certain induced voltages due to the charging of ion flow. Electrostatic discharge (ESD) may occur between two objects at different potentials when they are close ...
