7.4.2
High-speed measurements
In addition to the basic measurements, the PEM575 provides the following high-
speed measurements:
three-phase voltages (10 ms)
three-phase currents (20 ms)
three-phase power (20 ms)
λ
three-phase power factors (20 ms)
Neutral current (20 ms)
7.4.3
Voltage and current phase angles
Phase angle analysis is used to identify the angle relationship between the voltages
and currents of the three line conductors.
7.4.4
Energy
Basic energy parameters include
active energy (import, export, net energy and total energy in kWh)
reactive energy (import, export, net energy and total energy in kvarh) as well as
reactive energy related to the quadrants Q1…Q4
apparent energy (
S
ges
in kVAh)
The maximum value to be displayed is ± 999,999,999,99. When the maximum value
is reached, the register will automatically roll over to zero. The counter value can be
edited via software or through the front panel, password required.
7.5 Demand DMD
The demand is defined as an average consumption value over a fixed demand pe-
riod.
PEM575 supports the "Sliding windows" demand calculation; in addition to the de-
mand period also the demand cycles, which are to be considered, are specified he-
re. The following parameters can be set:
Synchronisation mode
– SLD
internally synchronised to the PEM's clock
– SYNC DI
externally synchronised to a digital input that has been program-
med as a demand synchronisation input (DI function = SYNC DI)
Demand cycles
