Note (1) - Bandwidth in AC in voltage = 3 kHz, in current = 2 kHz
Notes (2), (3) and (4) of the previous § apply.
Note 5 - In single-phase, the sign of the reactive power is determined by the
phase lead or lag between the U and I signs, while in balanced three-
phase, it is determined by the calculation on the samples.
Note 6 - Signs of reactive powers according to the four-quadrant rule (§4.2.12):
Quadrant 1 : Reactive power Q sign +
Quadrant 2 : Reactive power Q sign +
Quadrant 3 : Reactive power Q sign -
Quadrant 4 : Reactive powerQ
sign -
Note (8) - Measurement stabilization ~8 sec
