Reactive Power Controller Operating instructions

Reactive Power ControllerHarmonic thresholdsIn order to avoid resonancein the net and toprotect capacitors fromVoverload, a thresholdProgrow should be selectedfrom the threshold table. If a harmonic threshold is exceeded,capacitive stages are switched off for the durationof the discharge time.Setting range 0 - 10In order to avoid too much switchings of capacitorstages, the capacitor stages are only switched on, whenthe harmonic threshold of a lower threshold row is exceeded.If the threshold row is selected for 0, no capacitorstages are switched off. The thresholds of thresholdrow 0 are only taken as the lower threshold row forthreshold row 1.Example: Programming threshold rowLeaf to the harmonic table in the expanded programmingusing key 3. Confirm with key 1. In this examplethe threshold row 1 is indicated.Select the digit to bechanged by pressingVkey 2. The selected%digit is flashing.ProgChange the selecteddigit by pressing key 3.Pressing key 1 you leave the programming mode andwith key 3 you can continue leafing through the expandedprogramming.Harmonic thresholds in % of nominal voltageHarmonic numberThreshold row number1 2 3 4 5 6 7 8 9 103. 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.05. 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 8.5 9.07. 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.09. 1.2 1.2 1.5 1.5 2.0 4.0 4.5 5.0 5.5 6.011. 2.5 3.0 3.0 3.5 4.0 5.0 5.5 6.0 6.5 7.013. 2.0 2.1 2.5 3.0 4.0 5.0 5.5 6.0 6.5 7.015. 1.0 1.2 1.5 1.5 1.8 2.0 2.2 2.5 2.0 2.317. 1.5 1.5 2.0 2.0 2.3 2.0 2.5 3.0 3.5 4.019. 1.0 1.2 1.5 1.5 1.8 2.0 2.2 2.5 3.0 3.5Page 30= Key 1 = Key 2 = Key 3
