Mutual Inductance and Basic Operation Transformers
The transformer raises or lowers the ac voltage through mutual induction. The alternating current passing through the primary creates a time-varying magnetic flux through the core. This changing flux induces an alternating emf in the secondary.
As the current in the main coil growths steadily or falls steadily, there is a constant voltage induced in the minor coil. As the voltage in the first coil reaches extreme strength the voltage made in the minor coil is at its zero voltage. Thus, this is all about why transformers only work with alternating current.

Alternating current (ac) transformers by ron kurtus (revised 19 october 2013) a transformer is an electric device that is used to change the voltage in alternating current (ac) electric circuits. The ability of this device to change voltage is a major advantage of ac electricity over direct current (dc).
A current transformer is designed to maintain an accurate ratio between the currents in its primary and secondary circuits over a defined range. The alternating current in the primary produces an alternating magnetic field in the core, which then induces an alternating current in the secondary.
What happens when the primary of a transformer is connected to the dc supply. Why a transformer can't be operated on dc instead of ac? under what.
Extech ac/dc current clamp measures from two ranges 0 to 200 amps and 0 to 2,000 amps.
), is a type of “instrument transformer” that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary.
An alternating current is passed to the primary of the transformer and the measurement/sensing/protection device is connected to its secondary. The primary of a ct typically has only one turn, which is nothing but the current-carrying conductor passed through its window. It never has more than a very few numbers of turns in its primary.

The coils around the jaws serve as a secondary winding of the current transformer. Current flowing through the conductor generates an alternating magnetic.
We offer a wide variety of current sensors (also called current transformers, or simply cts).
Transformers change the voltage of an alternating current (ac) electrical supply. Some times transformers make the output voltage bigger than the input voltage, this is a step up transformer in a step up transformer there are more coils of wire on the secondary coil than on the primary coil.
Touted as the first digital ammeters with built-in current transformers, the aca- 20pc series directly measures from 0 to 2, 20, 50 or 100a.
However, if we connect a load resistor to it, an alternating current will go through the coil, in-phase with the induced voltage (because the voltage across a resistor and the current through it are always in-phase with each other). (figure below) resistive load on secondary has voltage and current in-phase.

The principle of operation of a current transformer is the same as that of the power transformer. The current transformer has a primary and a secondary winding. An alternating current flowing in the primary winding induces an alternating current in the secondary winding.
There are four typical types of current transformers: window, bushing, bar, and wound. The primary winding can consist merely of the primary current conductor passing once through an aperture in the current transformer core (window- or bar-type), or it may consist of two or more turns wound on the core together with the secondary winding (wound type).
