What is a Transformer? - Electrovo is a Transformer? A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a varying electromotive force (emf) or "voltage" in a second coil. Power can be transferred between the…
Transformer Failures, Causes & Impactiieng.org/images/proceedings_pdf/8693E0215039.pdf· PDF fileto leakage causes internal over-flashing. 3. Tap Changer Failure . The tap changer function in the transformer is to regulate the voltage level. This is done by either adding or removing turns from the secondary transformer winding. It is the most complex part of the transformer and also an important one.
