A Study of Insulator Breakdown Under Navy Antenna HV RF Conditions.

摘要

Conditions leading to initiation of corona streamers and breakdown in gases are reviewed. The effect of electric field strength at electrode surfaces and the pressure of the gas in the electrode gap on the acceleration of free electrons with the ions and molecules in the gas are identified. The presence of water drops or contaminants can reduce corona onset field from about 30KV/cm to about 6KV/cm,can affect the voltage distribution,and can cause heating in strong VLF fields.
