Automatic Power Factor Controller, Mode Automatic, Phase Single, Brand PENTACON

The accuvar family of var controller consists of with accuvar, One product serving as the foundation model. The accuvar is with designs, Microcontroller based that possess field proven for more than fourteen years. The main attributes of the var controllers are intelligent control the control parameter is var, And not pf. Target pf value is just used to calculate the capacitive var required to be added/removed to achieve the desired pf. E. G. If the target pf indicates that, Is unity the target var in the system is zero. If system kvar is 200 lagging, Then the controller needs to add 200 kvar of capacitor banks to reach zero var. The calculation of the reactive power in the system is carried out by taking instantaneous samples of all voltage and in all, Current waveforms four quadrants. These values are then subjected to dsp techniques to add a frequency independent 90 phase shift to current samples. The product of these voltage and current samples then generate signed var value. Var controller then takes into calculation the prevailing the prevailing, System kvar bank kvar and the bank sizes of and then, Each stage switches on/off the combination which is closest to the needed var.
