Power Transformer
Power transformer is also voltage transformer and used to achieve an accurate voltage ratio. The voltage ratio falls off as the load current increases. The difference between the full load and No-load voltages is usually expressed as percentage (regulations). In most cases the regulation is expected to be reasonably good in Power transformer which is distributed from the power station. It is used in Power house, Power Plants and Industries etc.
