New Energy Sources WhatsAppWith the capacitor in parallel, there is now an additional source of energy, which can take up some/all of the burden of supplying current to the inductive load (when it resists changes in current till it sets up its field), after which the source takes over again and recharges the capacitor.
New Energy Sources WhatsAppThe capacitors will therefore only be activated after the motor starts. Likewise, they may be disconnected before the motor is switched off. The advantage of this system is the ability to totally compensate the reactive power of the motor at full load. An optional damping reactor should be provided if several capacitor banks of this type are ...
