Power transformers

These industrial steam turbines can cater to 45 MW capacities up to 150 MW. Here is all that you need to know about power transformers:

Parts

These are the parts of a power transformer:

• Conservator – above the main tank, conserves the transformer oil.
• Steel Tank – the most crucial part, houses the windings, core, and other essential parts.
• Core – provides a path with low reluctance for the flow of magnetic flux.
• Buchholz Relay – protective device senses issues within the transformer.
• Breather – consists of silica gel, traps moisture from the air entering the transformer
• Windings – turns of copper coils, classified based on input, output, and voltage.
• Cooling Tubes – cool down the transformer oil.
• Tap Changer – balances the voltage in the transformer.
• Thermometer – used above 50KVA values, measures temperature within the transformer.
• Explosion Vent – above the conservator, expels boiling hot water out of the transformer.

Advantages

There are many benefits to the use of a power transformer, some of which are stated below:

• Easy construction and working principle
• Ability to step up and down the voltage and current
• Provide galvanic isolation with high efficiency, simple production, and reliability.
• Smooth power generation, transmission, and quick distribution.
• Cost-efficient.
• Types of transformers vary according to power, current, distribution, potential, and isolation.
• No internal moving parts and a long starting time.
• The potential to be reverse connected is dependent on usage type.
• Various input voltages are accommodated with multiple taps.
