Abstract

Using PCI data acquisition card, a digital acquisition system for partial discharge is developed based on VC++. A synchronization unit is designed to get the pulse peak and its phase information of partial discharge pulse. Frequency domain and time domain filtering method is used to denoise the digital partial discharge (PD) signal
