Description

technical field

[0001] The invention belongs to the field of electrical technology, and relates to an on-line monitoring technology for external insulation leakage current of substation power equipment, in particular to an online monitoring system for external insulation leakage current of substation power equipment based on virtual instrument technology. Background technique

[0002] For substation power equipment, especially those operating in industrial areas, coastal areas and saline-alkali areas, the current flowing through the dirty layer on the surface is affected by the three factors of voltage, pollution and climate. When the pollution on the insulating surface is serious, it will happen at any time Contamination flashover accident. Pollution flashover not only poses a serious threat to the safe operation of the power grid, but also causes huge economic losses. The present invention has successfully proposed and developed the external insulation leakage current mon...
