Volina is an ISO 9001-2015 certified company and the company is working as Isolation Transformer Manufacturers and provides the best Isolation Transformer in India . Isolation transformers are used to transfer electric power from alternating current (AC) power, achieved from a source, into some device or equipment while separating the powered tool from the source of power, done usually for safety purposes.
An ideal Isolation transformer eliminate impurities/harmonics to output supply and minimize potential difference between neutral to earth less than one volt .
