Transformer Oil
There was no oil used in the earlier Transformers. But it was the necessity of using some effective insulating medium in the Transformers. In the year of 1892, the General Electric Company first used insulating … Read more

Electrical Transformers with Theory of Transformers
Definition of Electrical Transformer The transformer is a static device that transforms electrical energy from one circuit to another without changing its frequency. The transformer works on the principle of mutual induction. Types of Electrical … Read more
Insulation of Transformer
In a transformer, we need to provide the insulation between the core and LV winding and also between the LV winding and HV winding. The insulation comprises of backlight and paper. The insulation system consists … Read more
Transformer Winding Concentric Winding and Sandwich Winding
There are two forms of transformer windings. One is a rectangular form and another is a circular form. In spite of that, transformer windings can also be either concentric or sandwiches. In a single-phase core … Read more
Transformer Core Types, Material, and Laminations
Transformer Core Power transformers work depending upon the principle of mutual induction between two or more magnetically coupled windings. The proper mutual induction requires an efficient linkage of magnetic flux between the windings. Therefore there … Read more
EMF Equation of Power Transformer
Whenever we apply an alternating current to the primary of a power transformer there will be an alternating flux created inside the transformer core. The flux inside the transformer core will link with both of … Read more
Power Transformer – An Introduction to Power Transformer
The power transformer is the most essential part of electrical transmission and distribution systems. In our current era, most of the electrical systems operate with alternating current or AC. After the production of alternating power … Read more
Reciprocating Pump Theory and Working Principle
There is a piston that moves to and fro inside a cylinder. This movement of the piston inside the cylinder sucks and discharges water or other similar liquids. When the piston moves in the forward … Read more
Jet Pump Working Principle and Theory
When the level of underground water becomes quite down we use a Jet pump. Because in that case centrifugal pump or other rotary pumps cannot lift the water from that down level. The working principle … Read more
Centrifugal Pump Construction and Working Principle
The pump which uses centrifugal force to lift water or any similar liquid to the higher head is the centrifugal pump. For lifting the water or similar liquid to the higher head this pump only … Read more
