Most of the electronic circuits used in Circuitstoday. Therefore, it is important to know the working principle, construction and types of transformers used in different analog circuits. A transformer can be defined as a static device which helps in the transformation of electric power in one circuit to electric power of the same frequency in another circuit. The voltage can be raised or lowered in a circuit, but with a proportional increase or decrease in the current ratings. In this article we will be learning about Transformer basics and working principle. The main principle of operation of a transformer is mutual inductance between two circuits which is linked by a common magnetic flux.
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in by Michael Faraday , and share several key functional parts. This is the most common type of transformer, widely used in electric power transmission and appliances to convert mains voltage to low voltage to power electronic devices. They are available in power ratings ranging from mW to MW. The insulated laminations minimizes eddy current losses in the iron core. Small appliance and electronic transformers may use a split bobbin, giving a high level of insulation between the windings. The rectangular cores are made up of stampings, often in E-I shape pairs, but other shapes are sometimes used.
A Transformer is an electrical device that can be used to transfer the power from one circuit and another circuit without physical contact and without changing its characteristics like frequency, phase. It is an essential device in every electrical network circuitry. It consists of majorly two circuits, namely primary circuits and one or more secondary circuits. In this discussion, we deal with different types of transformers. The mutual induction phenomenon between two or more winding is responsible for power transformation. There are several transformer types used in the electrical power system for different purposes, like in power generation, distribution and transmission and utilization of electrical power. The transformers are classified based on voltage levels, Core medium used, winding arrangements, use and installation place, etc.
There are various types of transformer used in the electrical power system for different purposes, like generation, distribution and transmission and utilization of electrical power. The different types of transformer are Step up and Step down Transformer, Power Transformer, Distribution Transformer, Instrument transformer comprising current and Potential Transformer, Single phase and Three phase transformer, Auto transformer, etc. This type of transformer is categorized on the basis of a number of turns in the primary and secondary windings and the induced emf.
Могу биться об заклад. - Он откусил кусок пирога и заговорил с набитым ртом. - Максимальное время, которое ТРАНСТЕКСТ когда-либо тратил на один файл, составляет три часа. Это включая диагностику, проверку памяти и все прочее.
