The power transformer is a step-up or set-down transformer that is used for the generation and transmission of power. It is used to connect two power stations and is used to increase or decrease the voltage levels as per the requirements.
The power transformer is a step-up or set-down transformer that is used for the generation and transmission of power. It is used to connect two power stations and is used to increase or decrease the voltage levels as per the requirements. At the same time, the Distribution transformer helps to step down the voltage of a transmission line to a certain safety level. It is used for domestic and industrial purposes.
Power transformers are different from Distribution transformers on the following basis:
- Type of Network
Power transformers are used for higher voltage transmission greater than 33kV, whereas, Distribution transformers are used to transmit lower voltages less than 33 kV
- Maximum Rating of Usage
Power transformers are used for ratings above 200 MVA. In contrast, Distribution transformers are used for ratings less than 200 MVA.
- Size
Power transformers are larger in size as compared to the distribution transformers.
- Designed Efficiency
Power transformers are designed for the maximum efficiency of 100%, which makes it a positive point, and the efficiency is calculated as the ratio of output power to input power, whereas Distribution transformers are designed for the efficiency of 50-70%.
- Setup
Power transformers usually have one primary and one secondary setup and even one input and one output setup. Simultaneously, Distribution transformers have one primary and two or more secondary setup.
- Losses
For power transformers, copper and iron losses take place throughout the day. At the same time, for distribution transformers, iron losses take place for 24 hours, whereas copper losses are based on the load cycle.
- Load Fluctuations
Load Fluctuations are significantly less in power transformers as compared to the distribution transformers.
- Operating Conditions
Power transformers always operate at full load, but Distribution transformers operate at a load less than full load as, under this, fluctuations are higher.
- Application
Distribution transformers are installed at distribution substations, whereas Power transformers are used in power generating stations and transmission substations.
- Flux Density
In Distribution transformers, the flux density is lower than that of Power transformers.
- Considering Time
Power transformers are independent of time limits, whereas Distribution transformers are restricted by the time constraint.
- Usage
Power transformers are used to step up or down the voltages, and, at the same time, Distribution transformers are used for the connectivity.
