Exp 7_ Regulation of Three Phase Alternator by EMF and MMF Method

[@rajtech....2244]

Good practical explain (very useful this pandemic situation covid-19)

[@prasanthkutty4114]

Thanks for video... Innum neraiya experiment upload pannunga.... Enakku purichuruchu.... Intha video laa... Wire connection lam video add panna nalla irukkum.... Next video la appadi podunga... I am EEE student... Please full detail oda video podunga sir.. Thanks

[@royarsofficial4788]

Very good explanation

[@vigneshs552]

Super bro

[@learnelectricalconcepts5210]

Thank u... I will upload the calculation very soon...

[@cheguevara1444]

Do we have to make current rated before doing oc test

[@learnelectricalconcepts5210]

First please conduct the OC Test and Conduct the SC test...

Very good video

what are the errors in emf and mmf method of computing regulation?😊

Thank u so much sir

[@rathinaswamyn4376]

Sir v curve and inverted v curve synchronized motor experiment video podunga sir

[@learnelectricalconcepts5210]

Ok bro... 👍

[@006ajay9]

Can you pl post video for ZPF (ZERO POWER FACTOR)

[@learnelectricalconcepts5210]

Sure 👍

[@thilakkannan6580]

Sir, 👌

[@santhoshk1635]

Sir please post zero power factor method calculation paduka

[@learnelectricalconcepts5210]

நிச்சயமாக.... 👍

No problem. I will upload the manual for this experiment very soon... Please take an assistance from any people who knows Tamil... Please read the below procedure and then watch this video... Procedure: 1.Note down the name plate details of motor and alternator. 2.Make the connections as per the circuit diagram. 3.Close the DPST switch and start the motor using 3-point starter by moving the handle slowly and completely. 4.If the rated speed is not attained, the resistance in the field rheostat of motor is increased until the motor attains the rated speed of the alternator. Open Circuit Test: 1.Keep the TPST switch in the stator side open. 2.Increase the field excitation (If) of the generator in steps by decreasing the resistance of the potential divider and the corresponding increase in the generated voltage (Eg) is noted down. 3.Continue the same procedure until the generated emf (Eg) reaches 125% of its rated value. 4.Reduce the excitation (If) given to the alternator to zero. Short Circuit Test: 1.Bring the alternator to rated speed by adjusting the speed of the prime mover. 2.Close the TPST switch in the stator side. 3. Increase the field excitation of the alternator slowly to circulate its rated current (Ia) through its armature (stator) windings and note down the corresponding field current (If). 4. Reduce the excitation (If) given to the alternator to zero. 5. Bring the field rheostat of motor to initial position and turn off the DPST switch.

Here I have uploaded the video with English subtitles. You can watch it now. I will add subtitles for all the videos very soon. Thanks for your comment.
