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:

0.25h

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:

0,1 Sec.

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.
