T
measured in units of Watts
where T is the period of the signal
On a CVI3, the Power peak is 5kW.
To dimension an installation, the apparent power consumption is the only needed information.
S = apparent power

measured in Volt-Amps (VA)
The apparent power peak is 6kVA the duration of the peak is < 0.5 s
The mean apparent power is always ≤ 1 kVA.
