| 摘 要： | 本文介绍电力电缆现场试验和诊断的现状和发展。直流电压试验作为一种对油浸纸绝缘电缆非常有效的方法应用至今 ,但它对塑料绝缘电缆是无效而且有害的。文中讨论了近几年以来开发的 0 .1Hz VL F法、CDA法、OWTS法以及变频谐振试验系统。用变频谐振试验系统进行的 2 0～ 30 0 Hz交流电压试验已被 IEC确认为高压和超高电力电缆的主要试验方法。

| Abstract: | The status quo and future development of on site testing and diagnositics of power cables are presented. The DC test, which is an effective means for the diagnostics of oil impregnated paper insulated cable, is still used even now, but it is ineffective and harmful for the plastic insulated cable. The 0.1 Hz VLF method, CDA, OWTS and frequency tuned resonance test system, which have been developed in recent years, are discussed. The test with 20～300 Hz AC voltage using frequency tuned resonance test system has been approved by IEC as the principal test method for HV and UHV power cables. |
