Averaging Time For The Mean Value Cos(Phi); Averaging Time Of Reactive Power - janitza Prophi Operating Instructions Manual

Reactive Power Controller

Averaging time for the mean value cos(phi)

Prophi measures real
and reactive work
within the averaging
time and calculates the
mean value cos(phi).
Setting range:
0.50h
1.00h
2.00h
12.00h
24.00h (presetting)
Example: Programming of the averaging time for the
mean value cos(phi).
Go to averaging time for the mean value cos(phi) in
expanded programming with key 3.
Confirm selection with key 1.
In this example, an av-
eraging time of one
hour is indicated and
flashes.
With key 2 and 3 the
desired averaging time can be selected.
Press key 1 for confirmation and with key 3 you can
continue leafing through the expanded programming.

Averaging time of reactive power

The measured reactive
power is summarized
within the averaging
time and the mean
value of reactive power
is calculated.
Setting range:
0,5 Sec.
1,0 Sec.
5,0 Sec.
10,0 Sec.
30,0 Sec.
60,0 Sec. (Presetting)
Example: Programming of the averaging time for reac-
tive power.
Go to averaging time for the mean value reactive power
in expanded program-
ming with key 3.
Confirm selection with
key 1.
In this example an av-
eraging time of 5 seconds is indicated and flashing.
Now the desired averaging time can be selected with
key 2 and key 3.
Press key 1 for confirmation and with key 3 you can
continue leafing through the expanded programming.
