Study on Measurement Error of Power Frequency Electric Field Intensity Caused by Change of Humidity on Surface Resistance of Field Intensity Meter Supports

Abstract This paper analyzes the different measurement results of field intensity meter in different environments, which confirms that humidity has a great influence on the support parameters of field intensity meter. In addition, by testing the actual electric field, the change of dielectric constant and resistance of field intensity meter and its support under different relative humidity conditions, and comparing the simulation results of COMSOL simulation software, it is concluded that the error of field intensity meter measurement results mainly comes from the influence of humidity on the surface resistance of field intensity meter support, and the relationship between the surface resistance of the support and humidity is obtained.
