Energy Metering

Metered values for active and reactive energy are determined by the device. They can be output via the display

of the device, read out with DIGSI via the operator interface or transmitted to a control center via port B.

Metered Values for Active and Reactive Energy

Metered values of the real power W

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 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.
