Single-phase AC voltage regulator capacity choice, according to the first aspect of the use of electric load is considered, began to select single phase AC voltage regulator of the capacity and size。 Assuming the single-phase AC voltage regulator capacity selection is too large, will not only increase the investment of equipment, but also cause long-term in a state of no-load transformer, without the use of its function and operation, the reactive power loss increases; but the single-phase AC voltage regulator capacity selection is too small, can make the transformer in the long-term overload state, so it is easy to burn out the transformer. Therefore, we are in for a single-phase AC voltage regulator capacity choice, to have a correct direction, it can save resources and energy in great extent.
Single-phase AC voltage regulator capacity choice, it should choose according to their economic capacity, or if it is the kind of load of asynchronous motor, according to its power to consider its capacity; even can according to the total power near lighting to selection of transformer capacity and the selection of single-phase AC voltage regulator based on the total power capacity the actual peak load may occur to. Such consideration not only let every family to ensure guaranteed, let each user to choose rest assured, for society, can save resources by using a back and forth。
In addition, each single-phase AC voltage regulator capacity level, should be reasonably according to the national standard of choice.
