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.

2.18.8.1 Description

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").

2.18.8.2 Setting Notes

Setting of parameter for meter resolution
Parameter 8315 MeterResolution can be used to maximize the resolution of the metered energy values by
Factor 10 or Factor 100 compared to the Standard setting.
