Working Mechanism

  • The AC flowing in the main winding produces an alternating magnetic field within the magnetic core.
  • The magnetic core then mutually generates an alternating current in the subsequent winding.
  • With low impedance, this transformer operates in a short circuit.
  • Consequently, the secondary winding's current is dependent on the main winding's current but independent of the load impedance.

Features

  • These split-core current transformers are used in panelboards and control panels.
  • These current transformers offer 5A secondary current.
  • They have a wounded window structure with accuracy for getting optimum values of primary ampere-turns.
  • These current transformers are offered in 25A and 50A current ratings.

Standards and Approvals

  • UL
  • CSA
  • ANSI

Frequently Asked Questions

What is the accuracy of Eaton split core current transformers?

0.30%

How to connect a current transformer?

  • A current transformer is connected in series to the current carrying conductor and an ammeter is connected to the secondary terminal.
  • When arranged, the ammeter provides a full deflection with either 1A / 5A, depending on the turn ratio of the current transformer.
  • The ammeter's scale is then adjusted according to the turn ratio.

What is the frequency rating of Eaton split core current transformers?

60 Hz
