A main key advantages to single phase transformer vs three-phase transformer is lower cost. The main difference between that the single-phase transformer is more appropriate for lighter equipment while in the three-phase transformer is used in the high power system. here this post gives the advantages and disadvantages of a single-phase transformer to better understand this topic.
Advantages of single-phase transformer:
- The cost of stand by the unit transformer is reduced.
- Any transformer can be switch off or maybe depending on their load demand.
- If two ad more transformer are connected in parallel the service continuity ensures and the system becomes reliable.
- If more transformed works in parallel the chance of overloading of particular transformer reduces.
Disadvantages of single-phase transformer:
- The maintenance cost becomes more.
- The space required for installing the transformed is more.
- When one or more transformer works on a parallel then chance of fault occurrence will e increased.
- The protective device of the transformer is more.
