2.Etching Area: Etching is to remove the redundancy electric pattern on wafer surface by chemical or physical method. The area where etching is implemented is called Etch Area.
5.The surface semi-conducting layer is widely used to control the electric field and suppress the surface corona discharge in both HV power cable termination and the end turns of HV generator stator winding.
6.The electric field, magnetic field, critical frequency, surface current, power transmission and attenuation, as well as TE and TM modes in waveguides are discussed.
8.Through a simple example, using finite element method to analyze the electric field distribution in HV insulation structure with surface semi-conducting layer is presented.
