摘要：Differential protection of a transformer is used in protecting the transformer windings against internal faults based on the simple property that the ratio of currents entering and leaving the transformer is equal to the inverse of the transformation ratio. This ratio is affected by either internal faults or inrush currents during transformer magnetization. In order to avoid mis-operation of a transformer differential protection relay due to inrush current, a distinction must be made between the inrush current and internal fault currents. This paper aims at using Self Organizing Maps to distinguish between the currents without delving into the particular differences in the properties of the 2 currents.
