Isolation Transformer

FEATURES

A transformer is a static electrical device which transfers power from one voltage level to another while keeping the frequency same. And, if the primary and secondary windings are coupled through a common iron core, they are considered as the Isolation Transformer.

•  The secondary winding, as usual in transformers, is physically and electrically isolated from the primary winding.
•  There is no literal electrical link between the two windings. They are magnetically coupled, not electrically linked.
•  This "line isolation" is a very desirable characteristic for various applications. As there is no electrical connection between the load and source, the transformer behaves like a filter between the two windings by segregating them from each other.
•  The Isolation Transformers significantly block the voltage spikes, switching transients and noise that originate in the supply side from being getting transferred to the load side.
•  Some isolation transformers are built with a turn ratio of 1:1. Such transformers are exclusively built to have the same input and output voltage and are used for isolation only.
•  All transformers except autotransformers provide isolation.
•  When used with a switching power supply, an Isolation Transformer prevents higher-order harmonic signals from degrading the performance of adjoining circuitry.
•  It is especially crucial in computers or other equipment incorporating microprocessors. Improper isolation can cause interference to other functions of the system and can cause excess ripples at the output voltage waveform.
