How to use transformer rating chart
The table above quickly provide rating current for a specific transformer rating and voltage.
If you have a transformer rating:
- Find the suitable table of Transformer (3 phase or 1 phase)
- Find the transformer rating in first column (for example, 500kVA).
- Find the voltage (line-line) you require on the top row (for example, 480V).
- The intersection of the row and column show the current rating (in this case, it would be 601A).
Alternatively, you can use online calculator on our site.
