2.18.8 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
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“).
2.18.8.2 Setting Notes
