Electrical power transformer types.

Core type transformer this transformer features two horizontal sections with two vertical limbs and a rectangular core with a magnetic circuit. These types of transformers are used for electrically isolating a device from the power mains for the purpose of preventing an electrical shock. 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. They are available in power ratings ranging from mw to mw.

In electrical step down transformers are used in electrical distribution system which works on very high voltage to ensure low loss and cost effective solution for long distance power delivery requirements. Electrical power transformer thus plays a vital role in power transmission. A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another or multiple circuits a varying current in any one coil of the transformer produces a varying magnetic flux in the transformer s core which induces a varying electromotive force across any other coils wound around the same core. One end of the primary of the isolation transformer is grounded earthed.

In instrumentation as well as in many electrical types of equipment step down transformer is the primary requirement for the power section. On the basis of design. Assembling three single phase transformers is quite pocket friendly to form a three phase transformer rather than purchasing one. 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.

It is cost effective to use auto transformer where the ratio between high voltage and low voltage is less than 2. Electrical transformers can be classified into different categories depending upon their end use construction supply and purpose. Three single phase transformers coupled together acts as a three phase transformer this device is mainly used for the industrial purpose to generate electric power transmission and distribution. Two winding transformers are generally used where ratio of high voltage and low voltage is greater than 2.

This type of transformer is commonly employed for three phase electric power systems such as power grids and transmission lines that they transfer large amounts of high voltages. Electrical energy can be transferred between. The transformers are classified based on voltage levels core medium used winding arrangements use and installation place etc.
