Transformers Maintenance & EMF Equation of a Transformer

Power transformer is most costly and essential equipment of an electrical system. It is well known fact that power transformers are the heart of the power systems which enables to establish very large power systems networks. Failure of any transformer will create critical situation in power distribution network hence extra attention is required in commissioning,… Read More »
