Technical manual
Directional operation can be combined together with the corresponding communication
logic in permissive or blocking teleprotection scheme. The current reversal and weak-
end infeed functionality are available as well.
The residual current can be calculated by summing the three-phase currents or taking
the input from the neutral CT.
