Thanks, even not understand Thai, I can follow the Math, as I also watch other video and calculate my case. Problem here: after have a PC as Server for 24/7 with shown by PZEM-014? modbus taking 50 W, at 225-230 Volt at 50 Hz causing shown PF of 0.78, I calculated need 2 uF to get it to near pf 1. - may not believe the data from modbus digital meter - may misunderstood the calculation as adding a 2 uF Capacitor the pf even get more bad, about 0.02 down to the calculation base 0.78 Now I stuck, seek for clearance and next days measure the data another way. Or is there a difference, if a unit/load is run behind a AC Inverter, even Online as this data is from ? I wanna redo with easier other PC I can shut down and switch to different meter, to first confirm data, before calculate again. But after this morning again for 5 hours just about 70 Volt deliver, sometime 140-150 I might have to solve other problems first. This has time ... BUT to reduce the lagging power is still important, reducing demand power at all, and so save costs to produce it at the beginning.
*คำตอบค่า capacitance กดเครื่องคิดเลขผิดนะครับ จริง ๆ เท่ากับ 110.912 uF
