Cummins 375kva diesel generator set price

In order to reduce loss of power in long distance transmission fever can be used in a way, there are two: one is to increase the voltage of cross-sectional area, the wire and bold, reduce the resistance;The second is to improve the voltage and current.The previous measures for requires a lot of metal wires, and very thick wire has many difficulties, so it is difficult to get adopted.After comparison, or a measures have practical value.However, for the use of direct current, the voltage increase or decrease is difficult to achieve.As a result, people have begun to consider using an alternating current voltage is easy to change.Point of view, it is easy to change the dc generator to alternating current generator is mainly take the commutator.Therefore, Siemens, Connecticut in 1873 invented the alternator.Since then, were the work of ac generator, so that the generator has been rapid development.
