NOTE!
To calculate the correct value of regenerating power it is necessary to note, that
the real momentary regenerating power is dependent on the real existing main
circuit voltage at any time. To calculate the regenerative power the following
formula should be used:

(during regenerative operation : cos

The maximum possible regenerative power is calculated based on the momen-
tary rms mains voltage and the maximum rms current of the respective device.
Example:
Model SVC(S) 45 with rated feedback power of 45kW , maximum rated rms
current 65A (refer to technical data), nominal mesh voltage rating e.g. 400V.
From that results: P=400V x 65A x

=45033W, that’s about 45,0kW
If the momentary rms mains voltage is only 395V or even lower for a short
time, the maximum possible regenerative power is reduced as well:
P = 395V x·65A x
√

= 44470W, that’s about 44,5kW.
