Figure 4 shows the demand Reactive power incurred Power factor in the on-off Cap.Bank. Figure 5 is a characteristic graph of Cap.bank worked do not meet the reactive power demand to quickly, resulting in on-load release or no load Cap.bank continues to work (Time delay) will be gradually removed at each step. and make over compensate effect, voltage is higher than normal.
As result make over compensate effect, voltage is higher than normal.
