Learn MoreAn induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC induction motor usually can be used as a generator, without any …
Learn MoreIf the active power demand falls below the generator''s active power output, then voltage rises, which damages the insulation of windings and can cause dangerous electrical discharges. Similarly, when reactive power generation is greater than reactive power absorption, the voltage increases, and vice versa.
Learn MoreOn the other hand, electrolytic capacitors find application in the start circuits of high-horsepower AC motors, offering high capacitance in a compact space. These capacitors are typically connected for intermittent use. Capacitors, alone or in conjunction with resistors, can form RC (resistor-capacitor) networks.

Learn MoreAs with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative. This means that a capacitor does not dissipate power as it reacts against changes in voltage; it merely absorbs and releases power, alternately. A Capacitor''s Reactance
