Figure. 5.2.1. - 38. Connections of ZCT scaling.

The residual I0CT scaling is set according to the zero sequence CT's ratings, in this case 200/1.5 mA

(see the image below).

Based on these values, the earth fault protection setting (1 × I0n) makes the function pick-up when the

primary current is at 200 mA (see the image below).
