An ideal transformer is a theoretical, linear transformer that is lossless and perfectly coupled; that is, there are no energy losses and flux is completely confined within the magnetic core. Perfect coupling implies infinitely high core magnetic permeability and winding inductance and zero
In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are
FARADAY’S LAW OF ELECTROMAGNETIC INDUCTION According to the Faraday’s law of electromagnetic induction, emf gets induced in the rotor. As the rotor circuit is closed one so, the current starts flowing in the rotor. This currents called the rotor current. This rotor
Control system engineering is the branch of engineering which deals with the principles of control theory to design a system which gives desired behavior in a controlled manner. A controlled system consists of highly integrated coordination of mechanical, electrical, chemical, metallurgical, electronic or
Gray Code is one of the most important codes. It is a non-weighted code which belongs to a class of codes called minimum change codes. In this codes while traversing from one step to another step only one bit in the code
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
