It analyzes the advantage of the scheme of high-voltage load switch current-limiting fuse combination,compared with traditional vacuum circuit breaker,in the protection of transformer up to 1 250 kV·A.

随着高压负荷开关-限流熔断器组合电器的出现，使得在操作不频繁、容量在1 250 kV·A及以下的场所，正逐步替代真空断路器，其中负荷开关用来开合负荷电流，以限流熔断器作短路保护，将控制与保护两种功能分开。

However, the generator may be disconnected from the grid in case of a disturbance such as a voltage dip even a grid fault.

然而在运行过程中，由于各种原因引起的电网电压波动、跌落甚至短路故障会影响发电机的不间断运行。

The antenna resonance is realized by adjusting the position of the short-pin,the slot width and relative distance of E-shaped.

通过调整短路针的位置，E形槽的宽度和相对位置实现谐振。

Since magnetic fields cause electrical currents, such a collision could have caused a monumental short circuit visible from Earth.

因此磁场产生了电流，这样的碰撞可以导致强烈的短路并且可在地球上看到。

Taiwan Gaoyin Company has opened up a new prospect in the global market monopolized by the United States and Japan and successfully developed nanometer diaphragm with extraordinary performances in electric capacity, discharge rate, micro-short cir cuit and cycle life, the thickness of which is only 10 micron.

台湾高银公司也研制成功了纳米隔离膜，厚度最薄可至10微米，产品的电容量、放电率、微短路和循环寿命等性能优异，打破了由美、日业者独占该领域全球市场的局面。

Firstly, a method to estimate the rotor speed, which is based on BP neural network, is introduced in this paper. Secondly, the Park Vector approach is used to monitor and diagnose the inter-turn fault of the stator winding. Finally, this paper studies thoroughly a novel approach to detect rotor bar breaking fault, which is based on the perfect combination of the Hilbert Transform and digital filter.

具体工作如下：采用BP神经网络对异步电动机转子转速进行无速度传感器估计；对定子绕组匝间短路故障，采用派克矢量方法进行监测与诊断；对于转子断条故障，详细介绍了一种新的基于希尔伯特变换与数字滤波的在线监测方法。

Solving the fault current distribution is one of the most important tasks in the research of electromagnetic compatibility in power system.
