Test to study the influence that wraps material besides capacitor and wrap technology game department discharge property , analyse to discuss different voltage to take off the property of partial discharge of various samplings. Through the analysis of the table picture of partial discharge for capacitor sampling, have reached the discrepancy of the different capacitor sampling discharge property that wraps material and have analysed the influence of different factor game department discharge property.
