  • AC Motors
    A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary (rotor

These combined effects of only drawing line current during voltage peaks and high harmonic content contribute to realizing a circuit that has an extremely poor power factor. Now consider what happens when a multitude of similar systems are on the same ac lines and all draw current

  • Solid-State ac Power Sources for Transformer Testing
    High-power electronics can now replace motor-generator sets for testing distribution transformers. * Solid-state ac-power sources combine the variable-frequency and voltage-power sources into a single package. * Tests sets are hardened against impulse events like those caused by lightning-strike
