Note (1) - Display of O.L
- Above 600 kvar in single-phase (1000 V x 600 A).
- Bandwidth in AC in voltage = 3 kHz, in current = 3 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 power Q sign –
Note (8) - In single phase, with deformed signals (THD and harmonics),
uncertainties are guaranted since
Ф > 30°. Additionals errors are following ,
depending of THD :
Add +1% for 10% < THD < 20%
Add +3% for 20% < THD < 30%
Add +5% for 30% < THD < 40%
