Functional Description
Metered Values for Active and Reactive Energy
Metered values of the real power W
p
and reactive power (W
q
) are acquired in kilowatt, megawatt or gigawatt
hours primary or in kVARh, MVARh or GVARh primary, separately according to the input (+) and output (–), or
capacitive and inductive. The measured-value resolution can be configured. The signs of the measured values
appear as configured in address 1108 P,Q sign (see Section “Display of Measured Values”).
Setting Notes
Setting of parameter for meter resolution
Parameter 8315 MeterResolution allows increasing the resolution of the energy metered values by the
Factor 10 or Factor 100 compared to the Standard setting.
