Abstract
A transformer bushing partial discharge monitoring chip device and method are provided. An acquisition unit comprises three sensor modules installed at end screens of three-phase bushings of a transformer respectively for acquiring partial discharge signals and power frequency current signals from the transformer bushing end screens; each of the sensor modules is connected to an SIP digitization unit through a wire; the SIP digitization unit is fixedly installed beneath a base of the acquisition unit for digitizing the partial discharge signals and the power frequency current signals; an output end of the SIP digitization unit is connected to an input end of a background processing terminal.
