电绝缘材料和系统 短上升时间和重复电压脉冲下局部放电 (PD) 的电气测量

[中文适用范围]： 本文件适用于由电力电子设备产生的重复电压脉冲应力下电气绝缘系统（EIS）中发生的局部放电（PD）的离线电气测量。 典型应用是属于由电力电子驱动的设备的EIS，如电机、电感电抗器、风力涡轮发电机和电力电子模块本身。 注：本文件与特定产品的使用可能需要应用额外的程序。 不包括在本文件范围内的有： - 基于光学或超声波PD检测的方法， - 在非重复性脉冲电压应力（如雷电脉冲或开关设备的开关脉冲）下的PD测量应用领域。 [外文原描述]： IEC TS 61934:2024 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 61934:2024 is applicable to the off-line electrical measurement of partial discharges (PDs) that occur in electrical insulation systems (EISs) when stressed by repetitive voltage impulses generated from power electronics devices. Typical applications are EISs belonging to apparatus driven by power electronics, such as motors, inductive reactors, wind turbine generators and the power electronics modules themselves. NOTE Use of this document with specific products can require the application of additional procedures. Excluded from the scope of this document 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. This edition includes the following significant technical changes with respect to the previous edition: a) background information on the progress being made in the field of power electronics including the introduction of wide band gap semiconductor devices has been added to the Introduction; b) voltage impulse generators; the parameter values of the voltage impulse waveform have been modified to reflect application of wide band gap semiconductor devices. c) PD detection methods; charge-based measurements are not described in this third edition nor are source-controlled gating techniques to suppress external noise. d) Since the previous edition in 2011, there have been significant technical advances in this field as evidenced by several hundreds of publications. Consequently, the Bibliography in the 2011 edition has been deleted in this third edition.
