What will happen when power factor is leading in distribution of power? Last Answer : If there is high power factor, i.e. if the power factor is close to one: 1. Losses in form of heat will be reduced, 2. Cable becomes less bulky and easy to carry, and very cheap to afford, & 3. It also reduces over heating of transformers....
Which power plant has high load factor? Last Answer : All base load power plants have a high load factor. If we use high efficiency power plants to supply the base load, we can reduce the cost of generation. Hydro power plants have a higher efficiency than thermal & nuclear power plants....
What is power factor? Whether it should be high or low? Why? Last Answer : Power factor should be high in order to get smooth operation of the system. Low power factor means losses will be more.it is the ratio of true power to apparent power. It has to be ideally 1. If it ... ex: 0.95 to meet actual power load has to draw less current (V constant), result in less losses)...
Define ripple factor. Last Answer : The ripple factor for a Full Wave Rectifier is given by. The average voltage or the dc voltage available across the load resistance is and RMS value of the voltage at the load resistance is called ripple factor....
