Where and Why are isolation transformers used?
The world of electronics is full of strange and unusual devices. And in a world where things only get weirder, isolation transformers are one of the most mysterious and confusing pieces of equipment on the market today. Isolation transformers are used to isolate circuits from electrical noise and spikes that could cause damage to sensitive instruments or systems. There are several manufacturers of industrial transformers. They can also be used in hospitals to protect electromagnetic fields and radio frequencies (RF). Isolation transformers are vital to use in hospital labs, where an electrical fault could prove catastrophic They can protect sensitive instruments from damaging voltages and current surges and provide a neutral path through the secondary winding of the transformer for single-point grounding in three-phase systems.
Isolation transformers also provide electromagnetic and radio frequency isolation between circuits connected by power cables or cable trays (see below).
