This paper introduces an on-line monitoring system for partial discharge of 10kV cable joint based on LabVIEW. After analyzing the mechanism of the production of partial discharge,the transfer characteristic of wide band current transformer for monitoring partial discharge current is calculated. The proposed current transformer can efficiently restrain the noise signal in electromagnetic induction part. Since the proposed on-line monitoring sys-tem was installed in a transformer substation,the LabVIEW monitoring platform can keep a lookout over partial dis-charge current of cable joints constantly. It can also monitor the cable joints accurately.
