Static P.F.C. equipment differs from the standard equipment for
the following reasons:
The reactive power regulator has a switching time of the banks
extremely quicker than the standard regulator
The device for switching the capacitors banks is electronic,
controlled by thyristors, with the capability of switching the
capacitors at zero crossing.
Static switching by thyristors has the following advantages:
Maximum speed in switching the capacitors banks (the total
power is switched in less than a second)
No current peak on the capacitors at the time of switching of
the banks
No voltage peak on the capacitors at the time of switching off
the banks
Elimination of deterioration of the contacts in the standard
contactors
Noise reduced to a minimum
Reduced maintenance
Prolonged capacitor life.
APPLICATION

The automatic static Power Factor Correction is particularly
suitable for variable quick loads, such as:
Injection presses
Elevators
High torque motors
Motors affected by voltage losses
Car industry
Wind
turbines for the production of electric energy
Diesel generators
