The device calculates the current power of the installation using the formula:
P = V*I*cos(φ)
 
  Where the voltage and the cos(φ) are the installation’s current values.
 The current is referenced in its full scale. (100% is the full scale of the device and a value above 
100% indicates that it is out of range).
