What is a transformer? Definition A transformer is a static electrical device that transfers alternating electrical energy (AC) from one circuit to another, without changing the frequency, through mutual magnetic flux. The working principle of transformer is electromagnetic induction, according to which a time-varying magnetic flux in the primary winding induces EMF in the secondary … Read more
introduction Electric pole transformers are an extremely important part of the power distribution system. It is also called Electricity Pole Transformer, Electrical Pole Transformer or Electric Transformer on Pole in common language. This transformer transmits high voltage electricity to homes, shops, and small industries by safely converting it to low voltage. How does Electric Transformer … Read more
Introduction In today’s modern electronic and power-electronic systems, signals are often in the form of pulses. The special transformer that is used to transfer such pulse signals safely, provide isolation and forward without distorting the shape is called pulse transformer. This transformer is different from a normal power transformer because its job is not to … Read more
Tap Changing Transformer is an electro-mechanical device. All the electrical equipment we use today is designed to function properly at a specific voltage level. However, the power supplied to electrical equipment can sometimes exceed or exceed its rated voltage. This can be due to a variety of factors, such as voltage drops in distribution lines … Read more
What is a Nickel–Cadmium Battery? Nickel cadmium batteries are a relatively new addition in the United States to the storage-battery family. These batteries consist of an interleaved assembly of positive and negative plates. Construction of Nickel–Cadmium Battery Cell containers are made of nickel-plated steel. Active materials, nickel hydroxide (positive) and cadmium oxide (negative), are encased … Read more
Introduction of the Edison Storage Battery. The Nickel–Iron–Alkaline battery is the result of an effort to avoid many of the disadvantages of the lead-sulfuric acid combination and is a radical departure from it in every detail of construction. The positive plate consists of hollow, perforated, sheet-steel tubes filled with alternate layers of nickel hydrate and … Read more
Introduction Cells in which electrical energy is stored in the form of chemical reactions and, through chemical reactions again, electromotive force is produced are called secondary cells. Lead-acid cells, nickel–iron cells, and nickel–cadmium cells fall under the category of secondary cells. Here, a description of secondary cells is given. Now let’s understand the lead acid … Read more
What Is a Battery? A battery is a device that converts chemical energy into electrical energy and supplies current for use.A chemical reaction occurs between the two electrodes and the electrolyte inside, producing EMF (Electromotive Force).When the battery is connected to a closed circuit, electrons begin to flow, and electric current is produced.From small watches … Read more
What is the Cooling of Transformers? Cooling of transformers is the process by which the heat generated in the transformer windings and core is safely removed to prevent overheating, insulation damage, and failure.This heat is mainly produced due to I²R losses, hysteresis losses, and eddy-current losses. Transformer Cooling Methods The main methods used to cool … Read more
