Nominal Ratio of current transformer

Equation and meaning

\[K_{n} = \frac{rated_{primary\_winding\_current}}{rated_{secondary\_winding\_current}}\]

Nominal Ratio (Kn) for current transformer

Variables in this formula

K_n — K N
Enter this value unless it is the selected unknown.
rated_primary_winding_current — Rated Primary Winding Current
Enter this value unless it is the selected unknown.
rated_secondary_winding_current — Rated Secondary Winding Current
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
