Esennar Transformers

Induction furnace Transformer The Induction furnace constructed with heavy copper tubing to its coil and it's designed with an inverter circuit that transfers the medium voltage to the coil. The magnetic voltage produced by induction coil induces eddy current and heats it. Medium frequency is important to reinforce the speed of heat generation. The inverter circuit needs D.C voltage for its operations which is obtained by converting available three-phase A.C voltage. Transformers which are used for converting existing three-phase A.C. voltage to Required voltage for converter circuit of the Induction Furnace is mentioned as Induction Furnace Transformers. Thus they are essentially Rectifier/ Converter Duty Transformers. Depending on the rating of the rectifier transformers , input voltage springs from standard three-phase AC distribution voltages like 433 V, 3.3 kV, 6.6 kV, 11 kV, 22 kV, 33 kV, etc. These become the first (or line side) voltage of the transformer. Se...

Oil Filled Transformers The  Oil Filled Transformers  are also called as Oil-immersed transformer features different voltages and power ratings Up-to 31.5MVA of 132KV. These highly efficient and reliable transformers provide the specified electric power supply without breakage or interruption. Transformer  oil the analysis provides a highly accurate indication of the internal condition of a transformer. Diagnostics tests, including oil quality, dissolved gas analysis, and furfuraldehyde levels.  When Oil Filled Transformers in operation, the heat of coil and iron core firstly is transformed into the insulation oil and then to the cooling medium. And consistent with the capacity sizes, it is often divided into an immersed natural cooling transformer and immersed forced air cooling transformer. The Measurement of oil filed Transformer is determined by the quality of insulating used. From industrial purposes to substations, oil-filled are installed. Need ...

Solar Transformer – Asset for Users Transformer plays a major role in solar energy production & distribution. Solar Transformer is the ability to withstand short-circuit tests. For transferring electrical power to the utility network inverter duty type solar transformer is widely used. Inverter windings are specifically designed to face up to voltages excursions that arise because of pulsed mode inverter operation. Multiple windings design on the primary side of the transformer enables one to connect two or more inverters to the grid with a minor number of transformers in total. Earth Shield is provided between the HV & LV windings to scale back the harmonics & path to ground any residual resonance. Sizing of those transformers may be a climacteric factor when planning a Photo-voltaic power station, as too large-rated power, can cause instabilities and economic disadvantages, also as too small transformer power, and won’t exploit the entire capability of the...

Power transformer manufacturers. Esennar transformers are the leading  Power transformer manufacturers in India.  Power transformers are generally used to step up or step down voltage levels in transmission networks. It is mainly operated during peak loads and has maximum efficiency at or near full load. In order to minimize losses across windings, high quality rectangular or round conductors are used for windings. The conductor is insulated with an enamel coating. The windings are designed to withstand impulse and over-voltages and ensure reduced axial stresses during short circuit conditions.   Mainly used for step up and step down applications in transmission networks, we use customized Pro-E software to design  electrical transformers.  By inputting the given parameters, a 3D view is simulated to understand the outcome. Using the software, it is possible to predict how the transformer will behave under electro-mechanical stresses, short circuits, an...
