Abstract

This issue features three articles, the first of which is “Advancing Space Charge Test Techniques: Pulsed Electro-Acoustic Measurement on a 525-kV HVDC Cable.” The aim of this article is to validate the procedure of assessing the effect of space charge accumulation in extruded HVDC cables. The article presents the results of a pulsed electro-acoustic (PEA) measurement following the protocol recommended by IEEE standard 1732–2017 (IEEE Recommended Practice for Space Charge Measurements on High-Voltage Direct-Current Extruded Cables for Rated Voltages up to 550 kV). A full-size, unaged HVDC cable rated to 525 kV was the chosen sample, with two tests conducted in positive and negative DC polarities. This study demonstrates the reproducibility of the PEA measurement on full-size HVDC cables over 100 meters in length and the applicability of the PEA measurement protocol in the IEEE standard 1732-2017.

本期有三篇文章，第一篇是“推进空间电荷测试技术：525千伏高压直流电缆的脉冲电声测量”。本文的目的是验证评估挤压高压直流电缆中空间电荷积累影响的方法。本文介绍了按照IEEE标准1732-2017推荐的协议进行脉冲电声（PEA）测量的结果（IEEE对额定电压高达550 kV的高压直流挤压电缆的空间电荷测量推荐实践）。选择额定525 kV的全尺寸、未老化的高压直流电缆作为样本，在直流正负极性下进行两次试验。本研究证明了PEA测量在长度超过100米的全尺寸高压直流电缆上的可重复性，以及PEA测量协议在IEEE标准1732-2017中的适用性。

期刊介绍： The EI Magazine publishes articles written by authors from industry, research institutes and academia. The articles are more practical in content than the papers published in the Transactions. Usually three articles are published in each issue. The articles deal with dielectric materials, processes and new developments applied to industry products. Also the EI Magazine is used to promote upcoming conferences and solicits papers for the conferences. In addition, reports on past conferences are given in many issues. Book reviews and news items are included. An editorial is written by both the EIC and the President of DEIS in alternate issues. Advertising of insulation products appears in many issues.
