This setting should be done carefully, because dependent on ambient conditions the compensation unit can
oscillate, when this setting is too small.
2.5.5.17 FAST CONTROL MAX. STEP SIZE
This setting limits the maximum capacitor power which can be switched-in in one switching operation. If too much
capacity is switched-in in one operation, this can cause unmeant reactions in grid.
The setting is done in kvar. If the setting is “0” (factory setting), there is no limitation.
2.5.5.18 FAST CONTROL AVERAGE Q
The number of mains cycles which are used to build the average of control deviation. Start for building the average is
after the measuring break is finished (2.5.5.16).
2.5.5.19 FAST CONTROL SYNC. IMP.
YES: the trigger pulse for switching the thyristor-switches is synchronous to the zero-crossing of the mains voltage (rising
sinus). This can cause a delay of the switching operation which is less one mains cycle.
NO: the trigger pulse for switching the thyristor-switches is coming directly after finishing the measuring of one period
+ run time for the algorithm (some µsec).
2.5.6 DISPLAY
In this submenu settings can be made according the display.
