how berry type transformer work
Answers
Answer:
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to one or more circuits. A varying current in any one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between the (possibly many) coils, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described the induced voltage effect in any coil due to changing magnetic flux encircled by the coil.
Explanation:
Core type transformers are popular in High voltage applications like Distribution transformers, Power transformers, and obviously auto transformers. reasons are,
High voltage corresponds to high flux. So, for keeping your iron loss down you have to use thicker core. So core type is better choice.
At high voltage you require heavy insulation. In core type winding putting insulation is easier. In fact LV(low voltage) winding it self acts as an insulation between HV (high voltage) winding and core.
