line reactor vs isolation transformer

  • Frequently Asked QuestionsLine Chokes Reactors

    Line reactors and drive isolation transformers are "two-way" devices high frequency spikes or notched generated on either the line input or by the load output will be attenuated before reaching the load output or line input respectively. In fact a line reactor will typically do a better job of noise attenuation than a drive isolation

  • The difference between isolation and regular transformer

    Nov 23 2005 · An isolation transformer is an ordinary transformer with primary and secondary windings. It usually has an equal number of turns on both windings so the input-output voltages are equal. Such transformers are commonly used on the AC mains to isolate (with very high resistance) an instrument from the power source.
