Characteristic angle
The power function is connected to the phase currents and a
phase-to-neutral or phase-to-phase voltage. The purpose of the
phase compensation is twofold:
· to compensate the phase difference between the phase volt-
age and the any measured phase-to-phase voltage
· to determine whether the function responds to active or re-
active power.
The following table summarises the most important operating
modes to
simplify setting the corresponding parameters correctly.
The angles given apply for connection according to the connec-
tions in Index 12.
The phase compensation also provides facility for changing the
direction of measurement or to compensate incorrect v.t. or c.t.
polarity.
