What is Parallel Operation of Transformers?
Parallel Operation Defined
Parallel operation of transformers is when multiple transformers are connected to increase system reliability, efficiency, and flexibility.
Maximizing Efficiency
Efficient parallel operation is achieved by activating only the transformers necessary to meet current demands, optimizing energy use.
Maintenance and Reliability
Parallel operation allows for maintenance without service interruptions and enhances reliability by providing backup capacity.
Conditions for Operation
Same voltage ratio of transformer.
Same percentage impedance.
Same polarity.
Same phase sequence.
Future-Proofing
This setup allows for easy adjustment to changes in power demand, either increasing or decreasing capacity as needed.
Advantage
To maximize electrical power system efficiency
To maximize electrical power system availability
To maximize power system reliability
To maximize electrical power system flexibility
