Ures Calculated zero sequence voltage Une the resonance point (Ipos Ires)
Alternative for
Ires, Iw, Ures:
Ires Last measured calculated coil position which the maximum zero
sequence voltage (Ures) was found
d Grid damping specified activated fixed coil can taken
into account (configurable)
k Calculated grid unbalance

Ires Last measured calculated coil position which the maximum zero
sequence voltage (Ures) was found
Iw Calculated active current component across the faulty section when a
low impedance earth fault occurs.Page 45
