Profile: Vandana Transformers is a manufacturer and supplier of transformers such as single phase & three phase transformers, isolation transformers, control transformers, auto transformers, CT & VT transformers and step up & step down transformers. Isolation transformers provide electrical decoupling or isolation to two connected circuits. They have a turn ratio of 1:1. This value is defined as the number of turns on the secondary winding divided by the number of turns on the primary winding. As a type of low-power device, isolation transformers are used to isolate the primary winding and secondary winding completely, and without affecting signal quality. By completely isolating the primary winding from the secondary winding, disturbances on the primary side cannot affect the secondary side. This makes isolation transformers well-suited for applications where spikes, high pulses, or lightning are likely or especially problematic.
