Facts About Power Transformers You Should Know

Transformers play a crucial role in various electrical applications, serving as the backbone for the secure and reliable transmission of electricity. Among the diverse range of transformers available, power transformers stand out as the most sought-after. True to their name, these transformers find primary use in electrical applications demanding high voltage and substantial current supply. Power transformers excel in facilitating the efficient transmission of currents between two or more electrical circuits by stepping up or down the voltage.

Aligned with the fundamental principle of electromagnetic induction, power transformers leverage various components within them. These include primary and secondary windings, a core, insulating materials, cooling systems, drain valves, and more.

Various Types of Power Transformers

Based on their functionality, application, and configuration, power transformers are classified into distinct types. Some transformers are designed to step up voltage, while others step it down. Additionally, transformers may feature either single primary and secondary coils or three primary and three secondary coils, the latter often employed in power plants as three-phase transformers. The main categories include:

• Step-Up and Step-Down Power Transformers
• Single-phase and Three-phase Transformers
• Auto-transformers

Key Considerations for Purchasing Power Transformers

Given the array of power transformers on the market, it is crucial to invest in the right one to suit specific applications. Purchasing from reputable manufacturers like Vandana Transformers is advisable. Consider the following factors when buying power transformers:

• Certification
• Voltage Rating
• Current Load
• Phases Required
• Power Rating
