The huge gap between demand and supply has put extra ordinary w Synchronous Rotating Reference Frame principle

The high level of harmonics, lowers the power factor, affects the
power usage and reduces component life. They also affect
performance of DG sets, transformers, cables and switch gears and
causes great drain on the power supply.
The harmonic pollution can be effectively controlled by making use of

Swan Active Harmonic filter
+
Swan is solid state, State-of-the-Art designed filter, which measures
level of current harmonic in supply line and eliminates it by generating
the counter harmonics. The control and reduction of harmonics
improves the power quality in multi-folds, making the electrical
distribution system highest efficient. The power savings to the tune of
10 to 40% is possible, depending on the applications.
+
Swan developed by DB , is useful for end users as well as to the
power supply companies. For the user, it helps in optimizing use of
available power, increases productivity, decrease utility charges and
+
improves equipment reliability. In fact Swan has many more
unparalleled features ; it is the single answer on power quality issues
for all types of applications.
