A.2 Current Transformer Description

A current transformer is a special kind of transformer that transfers energy

from one side to another through magnetic fluxes (see Figure A-5).

FIGURE A-5. Magnetic flux schematic

The formula for a transformer is as follows (Equation A):

* n

= i

* n

Equation A

Where i = amps and n = number of turns or windings

And where n

is the primary winding and n

is the secondary
