Pu stands for per unit and this will be used in single line diagram of power distribution and it is like a huge electrical circuit with no of components generators, transformers, loads with different ratings in MVA and KV. Those values are called as pu values. Operation carried out in Thermal power stations?
Both generator and alternator work on the same principle they convert mechanical energy into electrical energy. An RLC circuit carries an electrical circuit consisting of a resistor R and inductor L and a capacitor C , connected in parallel or series. This circuit is called a second order circuit as any voltage or current in the circuit can be described by a second order differential equation. Wire is sized by American Wire Gauge system. Your installation of conductors will depend on a few factors like gauge of the wire, wire capacity, etc.
Then click over to this article and find out the top 25 electrical engineering interview questions to clear the job interview panel. Electrical Engineering is the grassland of Engineering that usually deals with the learning and application of electronics, electricity, and electromagnetism. It deals with elevated voltage, particularly AC above the series of or V. Electric traction means with the electric power for the grip system. Electric traction means utilize of the electricity for railways, trams, trolleys etc. Nowadays, magnetic toehold is also used for projectile trains. And essentially dc motors are used for electric traction systems.
In today post, we will be sharing the frequently asked electrical engineering interview questions and answers related to electrical engineering. Electrical engineering deals with high voltage especially AC above the range of or V. When manufacturers design a transformer, they have no idea which kind of load will be connected to the transformer. The output of real power may vary depending on the power factor. A real transformer has the following losses;.
