Also, primary and secondary are conductively coupled. Why delta star transformers are used for lighting loads? When an armature core is in a magnetic field, the magnetic particles of the core tend to line up with the magnetic field. During no load condition most of the excitation current. The alternating flux links the other winding. When an alternating voltage is applied to one winding (called the primary), it sets up alternating flux in the core. This is the electrical engineering questions and answers section on transformers with explanation for various interview, competitive examination and entrance test. The transformer which works on single phase is called single phase transformer. Any circuits with this color is considered hot or live. Electrical engineering is a branch and discipline of electrical concepts and its applications related to electrical systems, electromagnetic and electronic devices.

Electrical engineer cover letter sample What is two winding transformer? An alternator converts mechanical energy into ac electrical energy, a generator converts it to ac or dc. The alternating flux links the other winding. (d) none of the above. In addition to the power transfer it. When the armature core is rotating, its magnetic field keeps. Electric traction means using the electric power for traction system (i.e. Any circuits with this color is considered hot or live. Magnetizing current (i m) which is in quadrature (90 0) to the applied voltage and in phase current which is in phase to the applied voltage. Current flowing through the transformer consists of two components.

Difference Between Current Transformer (CT) and Potential Transformer

Any circuits with this color is considered hot or live. The water is obtained in the boiler and the coal is burnt so that steam is obtained this steam is allowed to hit the turbine , the turbine which is coupled with the generator generates the electricity. Solved examples with detailed answer description, explanation are given and it would be easy to understand. When an armature core is in a magnetic field, the magnetic particles of the core tend to line up with the magnetic field. 300+ [updated] electrical engineering interview questions and answers. The main aim of this transformer is that the output power of the transformer is same as output power. The transformer which works on three phase is called three phase transformer. Operation carried out in thermal power stations? In these transformer only one winding is used as primary and secondary. What is six winding transformer?
