The value of the NGR to be inserted in the cicuit can be
calculated by the simple formula
R = V / (√3 * I)
Where V is the System Line voltage in Volts
I is the value of the fault current to be limited
In general practice the fault current is limited to the
full load rating of the largest equipment available in the
system.
