Importance of Transformers in Power Distribution
Transformers play a crucial role in electrical power distribution for several reasons:
Efficiency
High voltage can be transmitted over large distances; this is because, the current that passes through the wires will be low in value. Transmission and distribution substation also enable power plants to be sited away from load centers with acceptable losses.
Safety
Transmission voltages are high, and can be well above 300,000 volts; they cannot be used directly in a residence or an enterprise. These boils the voltages to safe values for consumers (either 110-250 volts for home use).
Adaptability
Different types of transformers are used depending on their application:
- Power Transformers: Commonly used at generating stations and sub stations, for voltage transformation.
- Distribution Transformers: Adjust the voltage for final use by the consumer.
- Isolation Transformers: Provide electrical insulation between circuits.
Thus, transformers are important apparatus that helps to construct the power distribution network and maintaining electrical energy safe for use with necessary voltage levels.
