the effect of power transformer
the transformer is composed of a wound on the same core of two or more than two of the coil winding, winding through the contact between the alternating magnetic field and according to the working principle of electromagnetic induction. transformer installation position should be considered for operation, maintenance and transportation, and should choose a safe place. the rated capacity in the use of transformer transformer should be chosen reasonably. the transformer no-load reactive power, need large. the reactive power to the power supply system of supply. transformer capacity if selection is too large, not only an increase of the initial investment, but also the transformer for a long time in no-load or light load operation, so as to increase the proportion of no-load loss, lower power factor, increase the network loss, this operation is not the economy and unreasonable. the choice of transformer capacity is too small, can make the transformer overload long, easy to damage the equipment. therefore, the rated capacity of the transformer should be selected according to the needs of the electrical load, should not be too large or too small.
