6 POWER 1. STAGE : [ 0.01 ... 255.99 ] kvar
To determine the controller's response sensitivity, the dimensions of the network's
smallest capacitor (stage 1) must be known. They are entered in two steps in kvar.
The integral kvar values (before the comma) are initially selected via the
é
/
ê
keys and saved with ENTER. The positions after the comma are then selected,
again via the
é
/
ê
keys. If the response sensitivity is being undercut, a warning
will occur ( indication of “!” in the display )
Save and continue with ENTER
7 TARGET COS PHI : [ 0.3 ind ... 0.3 cap ]
By setting the target cos phi, the power factor to be attained via the PF correction
is defined. It is also set via the
é
/
ê
keys.
Save and continue with ENTER
10 CONNECTING TIME [ 20...1000]ms
This refers to the time between connecting the capacitors to increase the
momentary network capacitance. It should be noted that in practical operation the
real connection time is affected by the discharge time (locking time).
Default setting: 1000 ms
Selection is performed via the
é
/
ê
keys. Continue with ENTER
8 MEASURING VOLTAGE [ 30 ... 525] V
Programming the measuring voltage. The values programmed here always refer
to the voltage at the clamps of the device!
The voltage is selected via the
é
/
ê
keys. Save and continue with ENTER.
9 V - CONVERTER RATIO [ NO ] possible: 230V...380kV / Vmeas.
When a measuring-voltage converter (e.g. for HV- measurement) is used, its
conversion ratio should be programmed here:
- Direct programming of the prim. voltage of the voltage converter
- - The sec. voltage is set automatically from the programmed meas.voltage under 8
Selection via the
é
/
ê
keys. Save and continue with ENTER.
