Wonderful. Keep it up.

Really well explained concept, I can't seem to remember if any one have done better than this

So many years it was difficult for me to read the chareceristics of motor , thogh dealing with big motors in cement industry ..now my understanding improved .

This is renga working in L&T ur videos are very useful ... keep posting ....

Thanks for sharing ur knowledge with us sir !

very clear good job, think you for your efforts

Thanks for such helpful vedio...👍👍

No dislikes at all Great man

when you understand it you can explain it ..thank you very much🙏

It is very much usefull

Thank you so much for this video. I really needed understanding of the same.

Thanks sir...clear for me now

Nice vedio,very useful

Thank you so much for the video. It is very useful for me to get a clear idea of characteristics of the motor thanks to your simple and brief explanation . For which I was searching for a long period of time.Please Upload the motor protection calculation you have told in the video.

Very good. Thanks 🙏🙏🙏🙏

Very Good!

Thanks 🙏

Thank you so much sir. you are great. Really first time , I got clearly understand the motor's characteristics. kindly also upload the video of motor protection setting calculation.

the best explanation, ur the saviour of electrical engineers

Super....,

Thanks for really a great technical video.. Please post video to explain differnt characteristics of protection relays

Excellent elaboration. Also make video on Generator capability curve. Thanks

sir please make a video for selecting setting for relay for motor protection.

thank you so much sir ..........induction motor operate in normal condition by fixed rotation and when a load is increasing the motor changes value of rotation how to explain that

For unbalance or single phasing protection in motor is there any standard setting. And how to calculate that one ?

Plz upload vedio,with fault current calculation for motor protection

Thanks a lot sir please do you have explaining your video in our website .....I am very very interested

I want your explaining of this video in your website

Thermal withstand curve also reflects stator core body current withstand capacity during earth fault ?

Sir pls clear hot run and cold start of motor .

Where to set the Motor thermal relay curve? Motor protection relay curve between Hot and cold withstand or below both?. I've read some papers which indicate to set the the protection between the hot & cold curves, but in the same paper indicate if only the hot curve is given, then set below. Should I use both element 51 and element 49 for the same motor?

Obviously to set belo hot curve.

Hello I would really appreciate it if you could help me resolve this issue. I have a 1000 rpm 160 kw rated 3 phase Delta connected ac motor hooked to an air compressor feeding an oxygen production plant. our phase to phase supply voltage is 380 volts. our maximum running load current at working pressure is 250 Amps. This motor failed as it was running for more than 10 years. Lately we demanded more continuous load due to high demand for medical oxygen effected by covid19 pandemic. I could not find a similar replacement available. However i found another German made motor with same mounting frame and shaft size and also 1000rpm at 50 Hz the name plate says: Delta connection 660 Volts - 260 Amps - 240 KW. my question is : if i supplied this motor 380V with same delta connection will it be able to give me 160 kw power? because its limiting design current is 260 Amps as it says . Thus if am assuming its rated power will be reduced proportionally to the reduction of supply voltage. i it is rated 240 Kw at 660 Volts is it true that it will become a 160 Kw motor under 380 Volts? I am also assuming it will not overheat as the current will not exceed its rated 260 A at my demanded compressor load. Please help me if you have a definitive answer without any speculations. Best regards

Honestly i am not very sure. Since the motor is a compressor motor so your understanding seems to be correct. But i would suggest that instead of connecting it directly you put a dry try transformer which will rise the voltage. Because connecting the motor directly will risk a huge amount of money.

@@electricaltechnologyandind5335 thank you for your feedback.

If I look at this curve, where do I get the motor acceleration data?

Should I use both element 51 and element 49 for the same motor?
