A Calculation Method of Very Low Frequency Transmitting Antennas Corona Voltage

The generation mechanism of very low frequency（VLF） transmitting antennas corona voltage was studied,and the physical phenomena and chemical reaction accompanying with corona occur. A calculation method of VLF transmitting antennas corona voltage was theoretical derived,and a calculation example was brought forward to illustrate the relationship between the value of antenna lead and the corona voltage. The research identified the roles played by the various contributing factors such as antenna diameter,surface roughness,atmosphere density,current frequency across the antenna lead,the state of get drench,the ice-cover degree of antenna lead,etc.
