Auxiliary transformer- current transformer

The current transformer is working based on two theories.

1.Ampheres law.

2.Faradays law.

Amp.law- whenever a current flows through the conductor it will produce magnetic flux around the conductor.

based on above principle- current flows through the primary will induce a magnetic flux in the CT core.

Faraday law- whenever a conductor cuts the magnetic flux or magnetic flux cuts the conductor will induce a emf across the conductor

based on above principle- the magnetic flux in the core will cuts the windings. so emf is induced across the secondary terminals .

whenever the secondary terminals connected with burden will make a closed path and current flows through the secondary to burden.
