What power plant has high load factor?
Diesel Engine has high load factor
Why a rotor of an alternator at rated power dissipates more heat at a low power factor load than at a high power factor load?
at lower power factor current drawn by load is high and at higher pf the current drawn is less...
Why ac motor has low power factor?
because of high resistance in the load.
Advantages of quasi z-source inverter?
quasi means half then VSI and CSI combined to maintain unity power factor.
What is standard power factor value?
The power factor measures the phase difference between a current and a voltage waveform. Power factor ranges from zero to one. A power factor of 1 is for a pure resistive load. Power factor decreases for loads like motors with high inductance. Power factor comes into play when determining the watts used by a device. Watts = Volts x Amps x PF. So ideally for efficiencies sake, you want to keep the PF as close to one as possible.
What are the advantages and disadvantages of unity power factor?
There is no disadvantage of unity power factor, because at unity power factor all the electrical power is efficiently utilized by the the load, and at lagging power factor some power is lost in the load's magneticfield.

What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
Why ac motor has low power factor?
because of high resistance in the load.
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
