Learn how distribution transformers work and the critical role they play in electrical power systems. In this video, Jake Braddock, Sales Manager, Dry-type Distribution Transformers, explains the fundamentals of low-voltage dry-type transformers. From how transformers work to key design characteristics used in industrial and commercial applications.
Whether you’re an engineer, electrician, or working in power systems, this guide can help you understand transformer basics, voltage conversion, or how to select the right transformer for your application.
Discussed in this video:
• What a transformer is and how it works
• Difference between liquid-filled and dry-type transformers
• How transformers step voltage up or down
• Understanding primary and secondary windings and turns ratio
• Transformer kVA ratings and current calculations
• Key transformer components: core, coils, insulation, and taps
• How tap settings adjust voltage output
Jake then goes on to explain the different types of dry-type transformers, including
• General purpose ventilated transformers
• K-factor transformers (harmonic loads)
• Harmonic mitigating transformers (HMTs)
• Totally enclosed non-ventilated (TENV)
• Encapsulated transformers
• Buck-boost transformers (voltage correction)
• Motor drive isolation transformers (VFD applications)
