In case of motor Power Factor Generally We Apply A Capacitor
But How Can We Know That A Motor is Running On Very low Power
Factor And What Rating Of Capacitor We Have To Place And Tell
Me Conversion Of Micro Farad to KVAR>
Answers were Sorted based on User's Feedback
generally now a days power factor is maintained by APFC ( auto power factor control) panel. Here there is a provision for setting the PF say 0.99. Capacitors from the capacitor banks are automatically switched off & on as per the load to maintain the set power factor. As motors are always run through motor control panel. As for the individual motor, we have to maintain the load for a suitable PF. Also C = kVAR / (2 π f V2) in microfarad

Why X'mer rating in kva only?
What_is_mean_by_negative_dc_voltage? why we use -48v except +48v in DC power supply systems.
When measuring the Insulation resistance of a motor winding (winding to earth) using a megger meter, Applied voltage(1000V) was automatically reduced to 500V. and the measured insulation resistance values are also very low (in Kohm range) Can anyone give me a reason???
why we maintain 50hz ,220volts,20Amp,ratings fixed every where in india,,electricity
