电绝缘材料和系统.在短上升时间和反复电压脉冲下局部放电(PD)的电测量

[中文适用范围]： IEC/TS 61934 是一项技术规范，适用于在电子功率器件产生的重复性电压脉冲应力下，对电气绝缘系统（EIS）中发生的局部放电（PD）进行离线电气测量。典型应用包括由电力电子装置驱动的设备的 EIS，如电机、感应电抗器和风力发电机。 本技术规范的范围不包括：基于光学或超声波的 PD 检测方法；以及由非重复性电压脉冲（如雷电脉冲或来自开关设备的操作脉冲）应力下的 PD 测量应用领域。 [外文原描述]： IEC/TS 61934:2011(E) is applicable to the off-line electrical measurement of partial discharges (PD) that occur in electrical insulation systems (EIS) when stressed by repetitive voltage impulses generated from electronic power devices. Typical applications are EIS belonging to apparatus driven by power electronics, such as motors, inductive reactors and windmill generators. Excluded from the scope of this technical specification are: - methods based on optical or ultrasonic PD detection, - fields of application for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulse or switching impulses from switchgear. The principal changes with regard to the previous edition concern the addition of: - an Introduction that provides some background information on the progress being made in the field of power electronics; - impulse generators; - PD detection methods; - a new informative Annex C covering practical experience obtained from round-robin testing (RRT); - example of noise levels, as shown in new informative Annex D.
