5.7 SINGLE / 3-PHASE BALANCED POWERS AND ASSOCIATED QUANTITIES

Particular reference conditions
Sinusoidal signals : cos ϕ = 1 - Frequency 45...65 Hz
Frequency measurement range : 0.5 Hz to 1 kHz (except on reactive power and DPF : 40...70 Hz)
!
On 3-phase, the measurement is only exact for sinusoidal signals.
Active power (W)
Measurement range
Accuracy
Resolution
NB : The measurement of active power has a ± sign.
Above 600 V/1000 A i.e. 600 kW, the display indicates "OL".
