Advantages of higher transmission voltage is/are Power transfer capability of the transmission line is increased Transmission line losses are reduced Area of cross section and volume of the conductor is reduced all of the above In multi quadrant operation of Electric drives quadrant I (first) is Forward motoring Reverse motoring Forward breaking Reverse breaking The number of solutions of the simultaneous algebraic equation y = 3x + 3 and y = 3x + 5 is: 1 2 0 Infinite The electric field at a point situated at a distance d from straight charged conductor is proportional to d inversely proportional to d proportional to d2 inversely proportional to d2 The basic function of a transformer is to change the power level the power factor the level of the voltage the frequency For time varying currents; the field or waves will be electrostatic magnetostatic electromagnetic electrical PWM switching is used in voltage source inverters for Controlling input voltage Controlling output harmonics and
