Power Distribution

This transformer data card is designed to provide a handy reference for those who need to select and apply dry type transformers.

Minimum data needed to select a transformer

• Load voltage (secondary voltage)
• Load requirement
• Three-phase (three wire or four wire)
• Single-phase (two wire or three wire)
• (load always determines phase of transformer)
• Load current (use table to convert to kVA or formula)
• Single-phase formula: Volts x Current = VA
• Three-phase formula: Volts x Current x ?3
• System voltage and frequency (primary voltage)
• Mounting location

Specific applications:

• Feeding distribution panel
• Energy efficient transformer
• www.us.squared.com/eexfmr
• Feeding distribution panel with harmonic content
• Non-linear energy efficient transformer
• Feeding multiple distribution panels with harmonic content
• Harmonic mitigation energy efficient transformers
• Small change in voltage
• Use buck and boost transformer
• www.us.squared.com/buckboost

GCF-inc will build most special dry type transformers that your application requires.
