APFC Panels:-
An automatic power factor correction unit is
used to improve power factor. A power factor correction
unit usually consists of a number of capacitors that are
switched by means of contactors. These contactors are
controlled by a regulator that measures power factor in an
electrical network. To be able to measure power factor, the
regulator uses a current transformer to measure the current
in one phase.
Depending on the load and power factor of the network, the
power factor controller will switch the necessary blocks of
capacitors in steps to make sure the power factor stays
above a selected value (usually demanded by the energy
supplier), say 0.9.
Syncronous Condenser:-
Instead of using a set of switched
capacitors, an unloaded synchronous motor can supply
reactive power. The reactive power drawn by the synchronous
motor is a function of its field excitation. This is
referred to as a synchronous condenser. It is started and
connected to the electrical network. It operates at full
leading power factor and puts vars onto the network as
required to support a system’s voltage or to maintain the
system power factor at a specified level.
