Ground Fault Turns Ratio
The controller also allows the user to adjust the Ground Fault Turns Ratio for applications where a
control module is monitoring GF using an external step-up or step-down current transformer. The ratio is
multiplied with the actual ground fault current measured to display the adjusted reading to the user. See
Section 5.8.2.2 for more details.
