In this paper, we designed and fabricated a partial discharge (PD) analyzer using the LabVIEW program for insulation diagnosis of power facilities. The prototype analyzer consists of a data acquisition module (100 MS/s) and a personal computer. A needle-plane and plane-plane electrodes were assembled to simulate insulation defects. In the experiment, PD pulses were distributed in phase of 40°~143° and 188°~290° for the needle-plane electrode, and 24°~120° and 230°~290° for the plane-plane electrode. The analyzer produces parameters needed for insulation diagnosis as the magnitude(q), the phase(Φ), and the numbers(n) of PD pulses.
