In DC current-excitation to transformer, why it sucks more current? Eventhough there is no power transfer between primary and secondary? R is very low so it should suck less current only na thn y its current increases?
2 5318inductance and capacitance may result in periodic reversals of the direction of energy flow,how???
1 3210For two systems transmitting the same amount of real power, the system with the lower power factor will have higher circulating currents due to energy that returns to the source from energy storage in the load.???
