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 …

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 …
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 …

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 …
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 …
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 …

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 …
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 …
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 …
