In recent years,in order to ensure the safe operation of power system,the partial discharge on-line mo-nitoring in GIS is becoming more and more important. So a multi-channel,high sampling rate data acquisition sys-tem is been needed to achieve real-time acquisition and transmission of discharge information. Developed data ac-quisition system,which used in GIS partial discharge on-line monitoring,based on the FPGA+DSP architecture. The system detects the signal of discharge by UHF and UE combined. While FPGA control sampling,data pro-cessed and sent by DSP. Simulating insulation defects in experimental setup of GIS to testing the system. The dis-charge position calculated by the signal conform to the actual situation. The system can achieve real-time acquisi-tion and transmission of GIS partial discharge information.
