The phase-sequence voltage components are calculated from the phase-to-ground voltages
when
VT connection
is selected as “Wye” with the formulae:
(Equation69)
(Equation70)
(Equation 71)
When
VT connection
is selected as “Delta”, the positive and negative phase sequence
voltage components are calculated from the phase-to-phase voltages according to the
formulae:
