Calculation formula for earth current values
The formula depends of nominal earth current:
0.1 to 40 Ion range
Line earth current value (primary value) = earth sampled value (e.g. word 10 or 14) * earth
primary CT / earth internal CT ratio (mapping address 0008=800) *
√
2
0.01 to 8 Ion range
Line earth current value (primary value) = earth sampled value (e.g. word 10 or 14) * earth
primary CT / earth internal CT ratio (mapping address 0008=3277) *
√
2
0.002 to 1 Ion range
Line earth current value (primary value) = earth sampled value (e.g. word 10 or 14) * earth
primary CT / earth internal CT ratio (mapping address 0008=32700) *
