Q nominal = S nominal
: The controller uses the nominal apparent power as
the nominal reactive power.
INFO
It is normally not necessary to change these defaults. The DEIF ML-2 products use Q nominal = P nominal.

P nominal
has the value entered in the Power (P) nominal
parameter.
S nominal
has the value entered in the Apparent power (S) nominal
parameter.
P nominal calculated
: The controller uses the nominal apparent power (S) and
nominal power factor (PF) to calculate the nominal power.
S nominal calculated
: The controller uses the nominal power (P) and the nominal
power factor (PF) to calculate the nominal apparent power.
3.3 AC measurements as analogue outputs
3.3.1 Introduction
You can configure an analogue output with the function for an alternating current (AC) operating value. This value may be measured
directly or calculated from the AC measurements. The controller then adjusts the analogue output to reflect the AC operating value.
Applications
An analogue output with a function for an alternating current (AC) operating value may be wired to a switchboard instrument, to help
the operator. For example, the total kW from a generator can be displayed.
Alternatively, an analogue output may be wired to a switchboard instrument, to help troubleshooting. For example, the voltage
unbalance between two phases (
Busbar | L-L unbalanced [V]
) can be displayed.
3.3.2 [Source] AC measurements
Assign the AC measurement function to an analogue output under
Configure > Input/output
. Select a hardware module with an
analogue output, then select the output to configure.
Function names
The [Source] AC measurement function names follow these formats:
[Source] > [Physical quantity] > [Equipment] | [Measurement] [[unit]]
. For example,
Shore busbar > Phase angle > Shore |
Phase angle L3-L1 [degrees]
.
