In previous work a noncirculating type of bearing current caused by parasitic capacitive coupling from stator windings to the rotor was identified.

在早先的工作中一非循环类型生由从固定子卷到转子的寄生电容的联结所引起的涌流被识别。

The analysis of data of inrush current and the experiment based on DSP indicated the effect of criterion.

采用实际变压器励磁涌流数据进行的分析和基于DSP 保护装置的程序实验表明该判据是有效的，具有一定的实际价值。

According to the curvature and convex-concave characteristic of the fitting curve, inrush current and fault current of power transformers can be distinguished.

该方法利用初始5ms内差电流的数据（5ms数据窗），将其拓展为长10ms的数据窗，然后通过最小二乘算法拟合差电流波形得到其近似表达式，再根据拟合曲线在各点处的曲率和凸凹特性来区分变压器励磁涌流和内部故障。

Utilizing the sample data within 5ms after fault initiation and extending the date windows from 5ms to 10ms, the approximate current formula can be extracted from fault current or inrush current using least square fitting method. According to the curvature and convex-concave characteristic of the fitting curve, inrush current and fault current of power transformers can be distinguished.

On the basis of comparing the feature of inrush current's grille curve with that of fault current, a novel transformer protection scheme is proposed, which is not affected by add-assist circulation current at delta side on Y/D connection transformer.

在比较励磁涌流与短路电流网格曲线各自特点的基础上，提出了一种新型变压器保护方案，该方案不受Y/D接线的变压器D侧环流助增作用的影响。

Little was visible but squares of a dusky orange-red on either side of the street, where the firelight or lamplight of each cottage overflowed through the casements into the dark world without.

除了街道两边昏暗的橘红色方块，几乎什么也看不见。透过那些窗子，每间农舍里的炉火光和灯光，涌流到外面黑洞洞的世界。
