A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core.

Farnell offers fast quotes, same day dispatch, fast delivery, wide inventory, datasheets & technical support. Types of current Transformer 1. Wound Transformer – In this transformer the primary winding is composed inside the transformer. The primary winding 2. Bar-type Current Transformer – The bar type transformer has only secondary windings. The conductor on which the 3.Toroidal Current Transformer Current transformer is an a.c equipment and it is used to measure the current through the ammeter and protect electrical equipment from short circuit current. And, working the principle of self inductance.

The current transformer has a primary and a secondary winding. 2020-06-29 · The turns ratio of a current transformer can be altered by using multiple turns. The example below shows how a 300/5 A CT can be used as a 100/5 A CT by using three primary loops to reduce the turns ratio from 60:1 to 20:1. This enables a higher rated current transformer to be used to measure lower currents.

Errors in Current Transformer. The errors that occurred in this transformer include the following. The primary winding of this transformer requires MMF (magnetomotive force) to generate flux which draws magnetizing current. The transformer’s no-load current includes an element of core loss component and occurs hysteresis and eddy current losses.
