We have seen in this series of turorials about the transformer, that when the primary winding of a transformer is energised, it produces a secondary

As well as stepping up (increase) or stepping down (decrease) a signal voltage, transformers also have one very other useful property, isolation. Since there is no

Thus far we have looked at the construction and operation of the single-phase, two winding voltage transformer which can be used increase or decrease its

Multiple Winding Transformers generally have one single primary winding with two or more secondary windings. But the beauty of transformers is that they allow us

Unlike the previous voltage transformer which has two electrically isolated windings called: the primary and the secondary, an Autotransformer has only one single voltage winding which is

The Current Transformer ( C.T. ), is a type of “instrument transformer” that is designed to produce an alternating current in its secondary winding which is proportional to the

This magnetic circuit, know more commonly as the “transformer core” is designed to provide a path for the magnetic field to flow around, which is

In the previous transformer tutorials, we have assumed that the transformer is ideal, that is one in which there are no core losses or copper

One of the main reasons that we use alternating AC voltages and currents in our homes and workplace’s is that AC supplies can be easily
