What are the uses of stepper motor?
Suppose a 3 phase, 2 pole, 440V induction motor is driving a flywheel of 600mm diameter, 150kg mass. By using v-belt and pulley, the speed is increased to 4500 RPM. What will be the effect on motor current?
why in an industry; machine having rated 200 h.p stopped after power factor is maintained above 0.97 lag by control panel in view-of energy saving
How to calculate the value of earth capacitance in a transmission line.
What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
