Have isolation transformers been replaced by the new technology of galvanic isolators?
Galvanic isolators do a good job, under ideal conditions, on just one of the many functions of an isolation transformer. If you can afford the cost, weight and space of an isolation transformer, use one. Youll be glad you did. It is helpful to understand what an isolation transformer is, in order to understand the many different roles that it performs. A transformer consists of an input winding and an output winding, all wrapped around a heavy iron core. It converts the electrical energy on the input side into a magnetic field, which then re-creates electrical energy on the output side. The input to output voltage ratio is simply a matter of the ratio of turns on the input and output windings. There is no electrically conductive path from the input to the output. Transforming this much power comes at a price: A 120/240v, 50amp isolation transformer will weigh a hundred pounds and costs about a thousand dollars. Please continue on, they are worth it! Here are the functions of an isolati
