25.8kV Protection device for main transformer using spacer current transformer in the 25.8kV GIS

摘要

The present invention relates to a peripheral voltage protection device using a spacer current transformer for 25.8 kV GIS, and more particularly, to secure supply reliability of a substation by expanding the secondary side protection range of the peripheral voltage, and to make the 25.8 kV GIS equipment compact. It relates to a peripheral voltage protection device using an improved 25.8kV spacer current transformer for GS so that space can be used efficiently by securing space and can also reduce manufacturing costs.
