Parallel Operation of Transformers
The transformer is said to be in parallel operation when their primary windings are connected to a common voltage supply and the secondary windings are connected to a common load. Advantages of Parallel Operation It increases the reliability of supply system. The size of transformer increases with the increase of its rating,its transportation and instalation is difficult.On the other hand transportation and instalation of small size transformers are easy. One ore more transformers may be taken under maintenance and the remaining will supply the load. Disadvantages of Parallel Operation Increasing short circuit current that increase breaker capacity.
