Instantaneous Current Curves (Ground Current Calculated)
The following characteristics is available:
DEFT (definite time).
Explanation:
The ground current can be measured either directly via a zero sequence transformer or detected by a residual
connection. The ground current can alternatively be calculated from the phase currents; but this is only possible if the
current transformers are Wye-connected.
