AI Technical Summary
Existing surface charge measurement technologies cannot perform large-scale online testing on the surface of operating GIS insulators, and neither electrostatic probe methods nor pulse acoustic electrometry can be used in high-voltage enclosed environments.
By constructing a GIS simulation model, preparing electric field sensing probes, collecting electric field signals using an array of electric field sensing probes, and combining this with a neural network model to perform charge inversion, non-invasive and non-contact online detection can be achieved.
It enables high-precision and reliable online measurement of charge density and distribution range without damaging the original GIS structure, adapts to complex electromagnetic environments, and enhances the engineering practicality of the method.
