Isolation Transformer 

Capacity :  1KVA to 500KVA

 

An Isolation Transformer has a Turns ratio of 1:1 and provides a complete galvanic isolation  between the Mains and the Load side. The basic function of an Isolation Transformer is to protect  the load from noise and spikes that appear in the mains utility supply. The other important function  of the Isolation Transformer is to minimize the earth to neutral potential that would arise due to  poor neutral conductor size and large neutral currents
