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]： 本文档适用于电力电子设备产生的重复电压脉冲对电气绝缘系统（EIS）进行离线局部放电（PD）的电气测量。典型应用包括由电力电子驱动的设备（如电机、电感电抗器、风力涡轮发电机）以及电力电子模块本身的EIS。 注：本文档与特定产品结合使用时可能需要应用额外的程序。 不在本文档范围内的有： - 基于光学或超声波PD检测的方法； - 非重复性脉冲电压（如雷击脉冲或开关设备产生的开关脉冲）应力下的PD测量应用领域。 [外文原描述]： 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.
