These transformers steps down or steps up voltage viz. 230 to 110 V or 440 to 220 V etc. They are available in auto wound or double wound constructions and in rating up to 500 KVA (for Single phase and three phase)...
Any Double Wound Transformer is inherently an ISOLATION TRANSFORMER as the primary and secondary are isolated from one another through insulation. However, modern machines and systems need a truly isolated, clean and stable power requirement. This...
