It means that the surge arresters step down the high
voltage of 150 to 20.

Answer / ashish

I Am Not getting u r Question Actually The Surge Arrestor
For Medium & High Voltage Substation is as
Voltage Rating Of LA ( KV )= 0.8* LINE Volgage of the
Substation.

here 0.8 is earthing coefficent factor for solidely
grounded system.....
