The importance of the parallel operation of transformers
- Reducing the total capacity of electrical transformers (as compared to separate their work). The decrease of total installed capacity is reached:
- By lowering the overall demand load to the diversity of loads connected to different transformers.
- By using a higher load rate of parallel transformers
- Less required backup in case of electrical transformer failure
- Reduction of electricity losses in electrical transformers due to a possible disconnection of unloaded transformers
- Improving the power quality due to the stable level of short circuit current throughout the network
- Increasing the reliability of operation of protective devices in the case of phase-to-earth short circuits in the network.
- Possibility of placing electrical transformers in operation phase-by-phase
