Constructional details of transformer ppt

Basic construction of transformer. Basically a transformer consists of two inductive windings and a laminated steel core. The coils are insulated from each other as well as from the steel core. A transformer may also consist of a container for winding and core assembly (called as tank), suitable bushings to take our the terminals. The primary winding has a large number of turns, and the secondary winding has a much small number of turns. For reducing the leakage reactance, the co-axial winding is used in the potential transformer. The insulation cost is also reduced by dividing the primary winding into the sections which reduced the insulation between the layers. Core construction 2. Transformer core for the power frequency application is made of highly permeable material. The high value of permeability helps to give a low reluctance for the path of the flux and the flux lines mostly confine themselves to the iron. well over are .

Nov 19,  · 1. CONSTRUCTION AND WORKING OF TRANSFORMERS PRESENTED BY: ARJUN PATEL rank-one.info(ME) sem 1 ROLL NO 2. CONTENT What is transformer Structure and working principle Construction of transformer Losses in transformer Ideal v/s practical transformer Uses and application of transformer 3. In Very Simple words. Transformer is a device which: Transfer Electrical power from one electrical circuit to another Electrical circuit. It’s working without changing the frequency. Work through on electric induction. When, both circuits take effect of mutual induction. Can’t step up or step down the level of DC voltage or DC Current. • The two windings of the transformer are called High voltage winding and Low voltage winding. • Both the windings are wound on a common core. • One of the winding is connected to ac supply and it is called primary. • The other winding is connected to load and it is called secondary. Sep 25,  · 1. TRANSFORMER • A transformer is a static device. • The word ‘transformer’ comes form the word ‘transform’. • Transformer is not an energy conversion device, but it is device that changes AC electrical power at one voltage level into AC electrical power at another voltage level through the action of magnetic field. Aug 03,  · Types by Design. All the transformer leads are brought out of their cases through suitable bushings. There are many designs of these, their size and construction depending on the voltage of the leads. Porcelain bushings may be used to insulate the leads, for transformers that are used in moderate voltages. The primary winding has a large number of turns, and the secondary winding has a much small number of turns. For reducing the leakage reactance, the co-axial winding is used in the potential transformer. The insulation cost is also reduced by dividing the primary winding into the sections which reduced the insulation between the layers. Basic construction of transformer. Basically a transformer consists of two inductive windings and a laminated steel core. The coils are insulated from each other as well as from the steel core. A transformer may also consist of a container for winding and core assembly (called as tank), suitable bushings to take our the terminals. And also core type transformer is easy to dismantle for repair. In shell type transformer, the coils are surrounded by core, therefore difficulty in inspection and repair of coils. V. Cooling: In core type transformer windings are exposed and therefore the cooling is better in winding than core. Core construction 2. Transformer core for the power frequency application is made of highly permeable material. The high value of permeability helps to give a low reluctance for the path of the flux and the flux lines mostly confine themselves to the iron. well over are .The two windings of the transformer are called High voltage winding and The two major types of construction of transformers (used in transmission and. Transformer Construction - PowerPoint PPT Presentation . It has various features including high dielectric strength, low vapor pressure, chemical inertness. The transformer is quiet simple in construction. Usually the core of a transformer is constructed with a material having high permeability, such as silicon steel. Transformer Construction. ECE 2.
