NOTE
l
Filter capacitance
P 2901[1] - C_Filt
is specified as the
capacitance value of the capacitors when using a delta
configuration! In order to calculate the capacitance per phase as
per the circuit diagram above, the device will internally multiply
the value by 3 (delta-wye transform). If the capacitors are
connected in a wye configuration, or if the capacitance of the
single-phase equivalent circuit is known, the corresponding
capacitance value must first be divided by 3 and then entered into
the parameter.
