Three phase multi tap transformer

three phase multi tap transformer

A three phase multi tap transformer is a transformer designed with multiple taps both on the input and the out of the switching transformer, one can apply multiple taps just to the input of the transformer or just to the output of the transformer. The purpose of switching transformers or multi-tap transformers is to feed various voltage to other switching equipment such as relays, contractors or related technologies in order to open or close certain circuits. The same can be applied in terms in input taps used to activate and deactivate the transformer specific tap. Transformers such as airport lighting transformers is a typical application for this form of switching transformer. Other application where switching transformers could be used would be for signal application where signal transformers supply multiple low AC output voltage to various sensing equipment.
