Research on the Influence of Environment Humidity to Power Frequency Electric Field Measuring Result with Suspended Probe

Power frequency electric field is a key factor of electromagnetic environment of AC transmission and transformation project. And the measuring result of suspended probe may rather larger with high environment humidity. In this paper, some experimental in the climate laboratory was completed to make clear the how environment humidity affect the measuring result. The experimental results indicate that the environment humidity has great impact to the measuring result of suspended probe. Meanwhile, the environment humidity can make the space electric field distorting through the holder. Hence, the measurement in high-humidity environment is not applicable for environment assessments.
