If the XLPE cable on-line monitoring system, which is based on the method of superposing a low DC voltage on the neutral point of PT ,is used in 6-35 kV power system, the way of grounding of potential transformers and the shielding layer of cable must be changed.

PE电缆在线检测系统应用于6～35 kV中性点不接地系统时，改变了PT中性点和电缆屏蔽层的接地方式，因此必须分析系统正常运行及故障状态下检测装置对电力系统的影响，以评价检测设备的实用性进行讨论。

Voltage sags may be caused by faults on the transmission or distribution system, or by the switching of loads with large amounts of initial tarting\inrush currents (motors, transformers, large DC power supplies).

电压下跌可由输配电系统中的故障引起，或由投切具有大初始起动电流；涌流(电动机，变压器，大型直流电源)的负荷引起。

I used it to drive, to excellent effect, both the solid-state Carver Lightstar amp reviewed in the April Fi and the tubed VTL MB-600s, which metamorphosed into MB-750s with the installation of VTL's new Signature power transformers.

我用它来驱动，以出色的效果，无论是固态放大器1.3666朗星审查在4月Fi和该管的VTL的MB - 600 ，它演变成的MB - 750s安装的VTL的新签名电力变压器。

The stations include converter transformers as well as air-insulated and gas-insulated switchgear.

转换站包括转换变压器以及空气绝缘和气体绝缘开关。

With the development of semiconductor devices, the switching frequency of PWM converters becomes higher, which makes PWM converters (mainly high-frequency transformers, inductors and capacitors in converters) smaller, and this will benefit design and application of them. Whats more, higher switching frequency will reduce the audio-frequency noise and improve dynamic response of PWM converters.

随着半导体器件技术的不断发展，PWM变换器所能达到的开关工作频率越来越高，使得变换器(主要是变换器中的高频变压器、电感等磁性元件和电容)的体积和重量越来越小，这有利于PWM变换器的设计及推广应用。
