Capacitor banks

Features

Traditional reactive power
compensation equipment
with electromechanical
contactors has a well
proven performance in
installations where the
load has slow  variations
and it is not very
sensitive to voltage
fluctuations.

Today, however,industrial
installations include
electronic equipment very
sensitive to voltage
variations (PLC, computers)
and also very fast changing
working cycles (automatic
welding machines,robots.)

Reactive power compensation
with static contactors
offers the best answer to
these new industry
requirements.
LIFASA automatic capacitor
banks with static
contactors use thyristors
instead of traditional
contactors.

The thyristors switch-on
capacitors on zero crossing
voltage, and switch them
off on zero current
situation.
This firing strategy grants
a totally transient free
switching of power
capacitors, avoiding any
problem with transient
overvoltages.
