    摘要: 本文件描述了在工频(45 Hz~65 Hz)下,使用液体污染物和斜面试样,评定严酷环境条件下使用的电气绝缘材料耐电痕化和抗蚀损能力的两种方法。
    ——方法1:恒定电压法。
    ——方法2:逐级升压法。
    方法1因无需连续观察,是较广泛使用的方法。
    试验条件的设计旨在加速效应的产生,但不是为了再现实际使用中遇到的所有条件。

    摘要: 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.

    摘要: This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes.OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of:- logical names of the various instances of the ICs, or objects, as defined in IEC 62056-6-2:2021;- data transmitted through communication lines;- data displayed on the metering equipment, see Clause A.2.This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc.To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately.NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators, thermal energy, gas, cold water and hot water.
