本指南介绍了使用DAC电压测试和诊断额定值为5 kV及以上的屏蔽电力电缆系统的实践和程序。它适用于用于传输或分配电力的所有类型的电力电缆系统。列表测试水平假设电缆系统具有有效接地的中性点系统或接地的金属屏蔽。

This guide presents the practices and procedures for testing and diagnosis of shielded power cable systems rated 5 kV and above using DAC voltages. It applies to all types of power cable systems that are intended for the transmission or distribution of electric power. The tabulated test levels assume that the cable systems have an effectively grounded neutral system or a grounded metallic shield.
