    • Types of Transformers
    • AutotransformersAn autotransformer hasonly a single winding, whichis tapped at some pointalong the winding. AC orpulsed voltage is appliedacross a portion of thewinding, and a higher (orlower) voltage is producedacross another portion ofthe same winding.
    • Constant Voltage TransformerBy arranging particularmagnetic properties od atransformer core, and installinga resonant tank circuit (acapacitor and an additionalwinding), a transformer can bearranged to automatically keepthe secondary winding voltageconstant regardless (withinsome limits) of any variance inthe primary supply withoutadditional circuitry or manualadjustment.
    • Polyphase TransformersFor three-phase power,three separate single-phasetransformers can be used,or all three phases can beconnected to a singlepolyphase transformer. Thethree primary windings areconnected together and thethree secondary windingsare connected together.
    • Resonant TransformersA resonant transformeroperates at a resonantfrequency of one or moreof its coils and (usually) anexternal capacitor. Theresonant coil, usually thesecondary, acts as aninductor, and is connectedin series with a capacitor.
    • Instrument TransformersThese comes in various types, such as:1.Current Transformers2.Voltage Transformers3.Pulse Transformers4.RF Transformers5.Baluns6.Audio Transformers7.Speaker Transformers8.Small Signal Transformers9.‘Interstage’ and coupling Transformers

    • Carbon Capture & Storage• Carbon capture and storage (CCSD) is an approach to mitigating climate change by capturing carbon dioxide from large point sources such as power plants and subsequently storing it away safely instead of releasing it into the atmosphere. Technology for capturing of carbon dioxide is already commercially available for large carbon dioxide emitters, such as power plants.• Storage of carbon dioxide, on the other hand, is a relatively untried concept and as yet (2007) no power plant operates with a full carbon capture and storage system. Currently, the United States government has approved the construction of the worlds first CCS power plant, FutureGen, while BP has indicated that it intends to develop a 350 MW carbon capture and storage plant in Scotland, in which the carbon from a natural gas fired generator plant will be stripped out and pumped into the Miller field in the North Sea.• Storage of the carbon dioxide is envisaged either in deep geological formations, deep oceans, or in the form of mineral carbonates. In the case of deep ocean storage, there is a risk of greatly increasing the problem of ocean acidification, a problem that also stems from the excess of carbon dioxide.
