Synchronous Distributed Partial Discharge Measurement System

Partial discharge measurement is a major diagnostics method of insulation systems in high voltage equipments, which makes it convenient to assess the insulation status and its prospective condition. Here the design of a distributed modular conventional system with the capability of synchronous operation is presented The system relays on an FPGA in each module for preprocessing and controlling purposes, where the PD signals acquired by each module are preprocessed for the extraction of common PD features in order to avoid superfluous data. The extracted potential features are temporary stored in external memories and finally delivered to host computer via serial channel for further statistical and mathematical analysis.
