What is a 3 phase transformer used for?
Three-phase transformers are used for power generation and electrical distribution network applications. They can be found in high power industrial loads such as rectifiers, motor drives, and other equipment.
What is the reason for using three-phase transformers in power systems?
Three-phase transformers are used in most electrical systems for power generation, distribution, and transmission. They are used to increase or decrease the voltage in a three-phase system.
What are the disadvantages of 3 phase system?
Disadvantages of 3 Phase System
- 2 overhead wires are required. So cost increases.
- System voltage 3.3 KV is less as compound to 25KV so because of low voltage, current is high.
- More current, more I.R (voltage) drop. So distance between 2 substations is less. …
- Composite System:
