Step-up Transformers with single phase and three phase are particularly employed for usages in which incoming power voltage demands to be increased. These are essential for a wide array of applications such as 3-Phase motors, 3-Phase pumps, heavy duty equipment, railways, industrial equipments etc. These are commonly employed in combination with phase converters, which use the ratio between the primary as well as secondary windings so as to increase the input voltage. Organized differently, Step-up Transformers with single phase and three phase are provided with have primary as well as secondary cores.
