Description

technical field [0001] The invention belongs to the technical field of electromagnetic measurement, and in particular relates to an automatic calibration device for a non-contact electrostatic voltage measuring instrument. Background technique [0002] Static electricity is a kind of electrical energy, which remains on the surface of objects, which is the result of the local imbalance of positive and negative charges, and is formed by the conversion of electrons or ions. Discharge occurs when static electricity accumulates to a certain extent. In areas where flammable and flammable mixtures exist in the surrounding space, when the energy of electrostatic discharge is greater than or equal to the minimum ignition energy of the mixture, that is, when the concentration is within the explosion limit range, explosion and fire accidents may occur. Static electricity may cause dust explosions, fires, and breakdown failures of large-scale integrated circuits. It is a potential majo...
