Thermal monitoring devices and methods for insulation of power equipment

摘要

Thermal monitoring devices and methods for insulation of power equipment.Eliminate capacitive leakage current from the leakage current detected by the neutral point converter of power equipment.Calculate the insulation resistance value of power equipment from the leakage current value that eliminates capacitive leakage current.Determine whether the insulation of power equipment has deteriorated based on the calculated insulation resistance value, in order to achieve electrical shock;It can accurately identify whether the insulation of power equipment that is expected to experience accidents such as fires has deteriorated.
