摘要

本文对变电所20kv网络中的一个缺陷进行了研究。在某些情况下，这可能导致危险的瞬态现象，与过压和电流循环有关。本文根据数字继电器记录的示波器，对这种情况进行了讨论，不仅给出了原因和影响，还提出了一些避免可能造成损害的建议。

The Effects of Short Circuits at Medium Voltage Transformers

The paper deals with the study of a defect in the 20 kV network at the power substation. In some cases this could lead to dangerous transient phenomena, associated with overvoltages and current circulations. In this paper such a scenario is discussed showing not only the causes and effects, but also some recommendation to avoid possible damages, based on oscillograms recorded by digital protective relays.
