Great Video SirJi. Highly Conceptual and Highly Practical. Thanks a Lot.

You are great !I watch your videos and comments given by viewers All teachers should follow your teaching process.May God give u strength to advise us.

So nice and simple equations can clear anybodies doubt. Great teacher.

Excellent way of simple explanation. Another unique video. Thanks.

Love you sir maiy wait kar raha hu aapke contactor load according calculation ke video ka 🙏

Very good and exclusive video.

गुरु जी बहुत ही बढीया समझाया धन्यवाद जी

Sir apka jawab nahi. Thanks sir it's very valuable video.

Very Nicely Explain Sir. Thank You

Very good video sir. It's quite helpful to understand the power factor concept. As usual I love the simple and unique way you explain things. Thanks.

thanks sir ,,,its very simple way.....

Dear sir, You are really amazing. Please can you let us know regarding ckt breaker rating and ampere frame.

It's very nice explanation and beneficiary to design pfi. But it should be more helpful if you calculate without the resistive load.

Best sir

thank you sir

Thanks to reply Sir.I can understand what you said but still i have doubt that what will clamp meter show in practically i mean how much current? Thanks

Nice video

Sir how to use crystal ,for making waveform in high frequency...... .??

Sir ek transformer impedance pr video bnao....... This one very useful

Kindly make a video on induction motors circle diagram and testing.

Please tell me how to install and calculate power factor

Also if there is a choke of input 440v 2 phase and output 1300 volts with current flow of 7 -10 amps in high voltage side should a capacitor be used to control the PF

Capacitor main permittivity badane par charging current ke effect par video banaye...

Kya dg ke sat capacitors bank laga sakte hai.

Sir 👍👍pls isska practical circuit video banayiye sir

So valuable topic Sir! Thanks for teaching us

Hello sir. I appreciate your effort and knowledge you share with us. I am electrical engineer working for yatch manufacturing comapny in germany i have one question about isolation transformer. Recently we have develop a new boat name sealine S-330V and we used petrol engine from mercury but our chife engineer used isolation transformer and he told me with use of isolation transformer we can provide better anode protection but i have doubt about that. Please explain me if this is possible or not? And is this logical to use isolation transformer in marine? Because when we connect boat with shore power we cant connect earth to shore connector as in such condition rcb getting trip.

@GKAgrawal2

The flow of currents in metallic parts in boat causes corrosion. When we connect to shore power with isolation transformer to a boat, the ground current loop can be avoided, this will limit the ground loop current in metal parts. So isolation transformer is used. If your RCCB is tri[ppping, perhaps earthing wire connection may not be proper. Or, the ground loop may be created due to water. I do not have the electrical diagram of such a system and also do not have much knowledge about yatch, so whatever little I know, I have shared in this comment.

Sir koi instrument hai jiska power factor unity nahi ho to kase decide kare ge ki inductor lagana hai ki capacitor, or uska vallue Kya hoga.plese reply.

Sir in practical is it possible to compensate an inductive load completely with a capacitive load to get the power consumption as low as possible or it has some limitations? Please elaborate. Thank you sir.

Yes it is possible, we have achieve it using continously variable capacitor system. Watch my video on inductor use at high voltage for power factor compensation.

Sir...power factor increase decrease hoga ta generator ka upar kya effect aega

Nice video Sir. But i have one doubt that's you have connected Resistive load together with inductive and capacitive load. Sir suppose if we have only inductive load and it's taking 6 amps and if we connect capacitive load across and capacitive load also taking 6 amps then how much Ampere will show on main Supply ?Please explain. Thanks

As explained in the video, both current will cancel out and net current in main should be zero. ( but currents will be flowing in L & C, circulating current) however, this is only theoretical, as, in the real world, we may not get an ideal capacitor and inductor. There will always be a resistor loss involved.

Hello sir 70 kw k lye ketna capestar lage ga

Sir ji, can you tell how will we take power factor in system , example a single line drawing of 5 floor hotel building. In each distribution borad, sub panel and the main panel we only assume the power factor to be 0.8 and do the rest of the calculation, like current, wattage etc... But when it's comes the question of power factor- capacitor bank , how will we calculate the existing power factor with load schedule, Theoretically...

Capacitor bank calculation for Apfc bank... If the current power factor is 0.9 and we have to improve it upto 0.999 Then take cos inverse of 0.9 and then take tan of that value..that is tan Phi 1... But our desired pf or target pf is 0.9999 hence take the cos inverse of 0.999 and then take the tan of that value.. That is tan phi 2... Then multiply the kva or apparent power with values of difference between tan phi values which we have calculated earlier... Kvar = kva ( tan phi 1 - tan phi 2 )...
