The isolation transformer is a type of transformer used to isolate a device or a circuit from the power supply. It provides galvanic isolation to the device. It has a turns ratio of 1:1 meaning that the primary and secondary of an isolation transformer contains an equal number of windings. ...
Iron core transformer:The main and secondary windings are both wound on several iron plate bunches, providing a great linkage path to the generated flux. Because of the conductive and magnetic properties of iron, it provides less reluctance to the linkage flux. These are common transformers with ...
Now, the voltage across the points B and C will be This constant is nothing but the turns ratio or voltage ratio of the auto transformer. Print Page Previous Next Advertisements
Transformer windings constitute the electrical circuit of a transformer. They are made up of current-carrying conductors wound around the core. The primary windings form the input to the transformer and the secondary windings form the output. The construction of the transformer windings should be ...

Step Down Transformer Step down transformers are used to step down heigh voltages i.e from 11000v to 220v or 110v and from 220v or 110v to 10, 12, 20 or 24 volts etc. Because the same magnetic flux lines cut both coils of a transformer, the induced EMF in the secondary winding, is...
Types of Transformer Oil: There are two primary types of transformer oil—paraffin-based and naphtha-based, each with different characteristics affecting oxidation and cooling efficiency. Electrical Properties: The electrical integrity of transformer oil is indicated by its dielectric strength, with a min...
The dividers described above can be made for dividing high voltages (2–3.5 kV) over a wide frequency range (20 Hz–200 kHz). The divider with its variable input resistance provides a convenient and rapid reading of the input voltage for a known output voltage and, owing to this, it can...
Types of Transformers Transformers can be categorized in different ways, depending upon their purpose, use, construction etc. The types of transformer are as follows: Step Up Transformers & Step Down Transformers- These transformers are generally used for stepping up and stepping down the voltage lev...
Any type of transformer is mainly constructed with three parts and those are core, a primary winding, and secondary winding. The core part is the important one where it provides a continual magnetic way having an air gap at the minimum level. This is constructed with plastic-coated steel shee...
