Test in three phase Induction motor
| Practical Demo|Dr Suresh.S|KIT|CBE. This video give you an idea about how to conduct an experiment to find the efficiency of the three phase induction motor by indirect test.
To good sir ....thank u very much ...I am from GEC Bharuch I did'nt attend the single practical in college but after seeing this I am able to understand the basics and it's application ......thank u very much sir
Welcome and all the best
Sir your video was very awesome and the content are very very well, thanks for your technical videos
All the best and wishes
Thank you very much sir your posting video please keep going so many video making please

Great video but complete havoc with wattmeters. First of all wrong selection of wattmeter types (LPF and UPF) which should depend on were they are connected and not on the type of test (no load or lock rotor). In both tests one wattmeter is subjected to low power factor [0•5]. Secondly the readings are obviously not -58 W and +100 W or whatever the author was saying. You need to apply multiplying factor taking into account selected metering range (10A, 500V). It made more sence to select 5A current range for no load test instead of 10A for negative wattmeter.
Also blocked rotor test selection of 600 V voltmeter range is wrong because it barely shows something. The same is true for the wattmeter. Why to select maximum voltage range if you know that the voltage in this test will not exceed 20% of nominal?
Despite being promissed the "calculations" part has never been posted. The reason for that is quite obvious- one can hardly calculate anything sencible based on these test results.
Sir if motor in full load condition in that watts meter it should show 3500 watts because motor is 3.5kw rated motor but I meter it shown 104 watts only so may i know why?
Thank you sir❤
Very Nice sir...
If i am not wrong the starter that you have mentioned is Manual Star-Delta Starter not a Semi automatic one...
Yes
Sir,
I am 3rd EEE...
I want to how to join internship programs or technical industry training atha pathi video podunga sir...
EEE Related aa ennana useful softwares learn pannikalam...
Power of motor
Sir I had one question we had an hydraulic system for that we use 30 kw motor for this 30 min only that hydraulic system works remaining time it's run ideal running only so how to calculate power consumption for this motor?
AC induction motor
Dear sir where is ur located ur institute. I want to join nd how much is ur charge please tell me.
sir ji.....thanx for video.. but where is calculation part?
See another video part 2
Verithanam sir
super
nice.......

Sir kindly add second video
i m studying 1st year sir,i had joined an integerated msc course sir, can i discontinue from it and apply for tnea 2020 counselling and join in other engineering college
sir what about the calculation, you tell you make a separate vedio on this.
Okay

Sir kit college pathi explain aa video poduga sir, autonomous or deemed? Solluga sir
Sry i can't explain abt any college it makes lot of issues. .Tat too if say abt my campus people will say advertisement.... So if u wanna learn more abt KIT.come in private chat.so have a glance in website :kitcbe.com
@@sureshseetharaman5 ok sir
Sir nano engineering pathi pesunga sir
Sir please in the case when rotor block in squirrel cage how much the value of Ws ?
It's depends on machine rating
@@sureshseetharaman5 how are you sir please give me your email or Facebook or anything I need you please
@@sureshseetharaman5 but it changing with velocity or it remains standard (the value)
Sir tq
Sir sc test me input supply kaise control kiya
But Autotransformer only Apply very very minimal voltage
You forgetton about calculation of the test so include that for better result
Sir can u please uploed synchronous motor v and inverted v experiment.?
Sure and very soon will upload.
Sir where is second part?
Pl check as part 2
@@sureshseetharaman5 no sir, i didnt get the part 2 vedio?
So we saw that during blocked rotor test , the supply voltage was increased gradually but current increased very rapidly, how come motor showed it's characterstics without 415 V?
Its a fully loaded machine....Load is maximum significantly current shoots ..It behaves almost like shortckt..With reduced voltage...
@@sureshseetharaman5 one more question sir, in load condition and on load condition (50% load), will the rpm decrease or will remain constant
Sir tnea cut of eppadi sir calculate pannarathu

Yes
Why this question
