I’m pursuing my engineering from G H Raisoni Collage Of Engineering, Nagpur , Maharashtra, I’m studying in 3rd in Electrical Engineering and my self Vishal Deshmukh .. I have 68% in 10th because I represent Maharashtra in National Kabbadi Turnament so that reason behind my low percentage in 10th and my pointer from 5th sem is 8.20 and SGPA from 2nd year is 8.89 so I can eligibal for your company
mathematically cos of the angle between voltage and current physically the angle measure the active and reactive power . the reactive power back to the source again , the angle measure that value
the power factor of an AC electrical power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit, and is a dimensionless number in the closed interval of −1 to 1
In order to insulate and to provide cooling to the windings we use transformer oil. Transformer oil has very high breakdown voltage so that it does not breakdown inspite of having high voltage coils around it. When transformer works on high load its winding temperature increases hence oil temperature also increases which then cooled through the cooling tubes having contact with outside air.
Cooling purpose , transformer oil is insulation oil also
Called as also insulation oil and this is stable at high temperatures.
1]An electrical engineer is responsible for designing and developing new electrical systems 2] Test equipment and finds solutions to electrical problems and devices. 3] Electrical engineers usually work with large-scale electrical systems which include motor control and power transmission.
