Motor input = P = 5 kW Original P.F = Cosθ1 = 0.75 Final P.F = Cosθ2 = 0.90 θ1 = Cos-1 = (0.75) = 41°.41; Tan θ1 = Tan (41°.41) = 0.8819 θ2 = Cos-1 = (0.90) = 25°.84; Tan θ2 = Tan (25°.50) = 0.4843 Required Capacitor kVAR to improve P.F from 0.75 to 0.90 Required Capacitor kVAR = P (Tan θ1 - Tan θ2) = 5kW (0.8819 - 0.4843) = 1.99 kVAR And Rating of Capacitors connected in each Phase 1.99/3 = 0.663 kVAR
Sir, video is absolutely good and self explanatory. But Please note that NO never become NC or Nc becomes NO. NO closes it’s contacts and NC opens it’s contacts by external switching action. Please do not use term NO becomes NC or NC becomes NO.
Bahut hi badhiya apne description diya apne
Nice
Nice sir single phese janretar ka automatically daigram bhejna sir
ok i will send
Good video.
thanks
Good
Awesome video sir
Thanks
eska vidio seyr kijiy
sir perfectly explained but can u show it with panel contactors and all
Ok next video
Aapko. VDO Dekha and comment vi Kiya lekin Aapne reply Nahi Diya kyun sir ?
Sir explain the with axillary contecter
sir if we use six stage capacitor bank then how many NO are used .
Nice sir
thanks
Hi
Pawer waring ro interloking karke deakgo sir
Relay keise kam karta hei
There six contactor . How many manual contactor is necessary to using N.O point. If we have
add on block used
kya capacitor bank use hoo skata he choke wale generator ke sath
yes
How capacitor useing calcult
Motor input = P = 5 kW
Original P.F = Cosθ1 = 0.75
Final P.F = Cosθ2 = 0.90
θ1 = Cos-1 = (0.75) = 41°.41; Tan θ1 = Tan (41°.41) = 0.8819
θ2 = Cos-1 = (0.90) = 25°.84; Tan θ2 = Tan (25°.50) = 0.4843
Required Capacitor kVAR to improve P.F from 0.75 to 0.90
Required Capacitor kVAR = P (Tan θ1 - Tan θ2)
= 5kW (0.8819 - 0.4843)
= 1.99 kVAR
And Rating of Capacitors connected in each Phase
1.99/3 = 0.663 kVAR

Sir, video is absolutely good and self explanatory.
But Please note that NO never become NC or Nc becomes NO.
NO closes it’s contacts and NC opens it’s contacts by external switching action.
Please do not use term NO becomes NC or NC becomes NO.
