Directional impedance element for mho characteristic ZDMRDIR
The evaluation of the directionality takes place in Directional impedance element for
mho characteristic (ZDMRDIR). Equation
and equation
the fault is in the forward direction for phase-to-earth fault and phase-to-phase fault
respectively.
