From the system view, this mode supplements capacitors to the line up to closely three times the fixed capacitor
. This is the normal operating mode of TCSC.
For single phase motor a promising method is to emulate a variable capacitor, starting from a fixed capacitor
and the value of this being modified by electronic variable duty cycle commutating it at a higher frequency
We notice that one may be below the target factor sometimes, because this may allow one to choose a smaller fixed capacitor
, as opposed to a larger switched capacitor bank.
The StacoVAR[R] ME line of fixed capacitor
assemblies provides power factor improvement for applications from 2 to 200 kvar.
In fixed frequency oscillators, the varactor and its bias choke and bypass capacitor are replaced with a single fixed capacitor
, and capacitor [C.sub.TF] is eliminated.
