The lightning protection wiring of the transformer connected to Y and yn connected to the overhead line is as shown in the figure. Install the FS-10 valve-type arrester on the high-voltage side of the transformer ; install the FS-O.25
, FS-O.5 valve-type arrester or MY-440, MY-440V type, with a flow rate of 10-20kA on the low-voltage side. sensitive resistor or
breakdown protector. Grounding resistance requirements: Transformer capacity is less than 100kV. When A is io,ri, it is greater than or equal to 100kV.
