Hi all, I have this problem regarding power factor correction. I was wondering if someone would tell me how I need to work it out. thanks;
A single phase motor operating off a 400v, 50Hz supply is developing 10kw with an efficiency of 84% and a power factor of 0.7 lagging. Calculate;
a. the input apparent power
b. the active and reactive components of the current
c. the reactive power (in kilovars)
it is required to raise the supply power factor to 0.9 lagging. Determine the value of the capacitance required in parallel with the motor to achieve this correction
if someone knows the solution please e-mail me on malachyp@gmail.com thanks.
