2.23.9 Energy Metering
Metered values for active and reactive energy are determined by the device. They can
be called up at the front of the device, read out via the operating interface using a PC
with DIGSI, or transferred to a central master station via the system interface.
2.23.9.1 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, sepa-
rately according to the input (+) and output (–), or capacitive and inductive. The mea-
sured-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 Val-
ues“).
2.23.9.2 Setting Notes
Setting of parame-
ter for meter resolu-
tion 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.
