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 is too low then cable over heating & equipment overloading will occur. if it is greater than 1 then load will act as capacitor and starts feeding the ...

The power plants which are used to take the baseload, run on a high load factor and the plants which are used to take the peak load run on low load factor, higher the load factor the lesser will be the cost of power generation per unit for the same maximum demand. High load factor is a desirable quality of power plant. Higher the load factor ...

In the low load region, current measurements are not a useful indicator of load.

The raw mill motor, fan motor and the coal mill motor have a power rating higher than 200 kW and are therefore directly connected to the 6 kV bus of their respective medium voltage substation. Due to their power, each of them has a liquid starter instead of an oil starter, which permits a continuous reduction of
