Polarity Test of 3 Phase Induction Motor | Correct Identification of Motor Terminal ( Part-1)

Polarity test of 3Phase Induction motor is very essential if their is interchange of terminal polarity. There is various methods for polarity test, but in part1, we try to explore a method of polarity test using voltage test method.
Also watch Part2 of thos video for Polarity test using series test method.

Excellent video sir...this is is a very confusing and misunderstood concept which has been explained very clearly in this video. I dont think any other video has addressed the issue both mathematically and practically. Another video using the DC method would be really appreciated. Well done !

[@rajkumarlavangare1462]

First time I noticed on you tube correct identification is done by polarity test .
excellent share

[@ritikraushan7392]

Can it affect if motor start rotating due to 230 volt supplied in single phase ,and how to avoid high current drawn by motor due to single phase supply , as resistance of motor is very low in milli ohm .

Auto tfr se voltage kam kar ke test kijiye

[@rajeshjana1006]

Very good sir

[@amankumarsingh2200]

Awesome explanation..... Just loved it😍.....I wish you grow more and more and spread the light of knowledge all aroud the world.... Once again thank you so much.... I can't explain how much I needed the phasor diagram explanation of this test.... 🙏🙏🙏🙏

@@electricaldesifunda Sure🤩 !

Regarding with the phasor diagram for your sketch, i had litle confusion on your sketch left side V should be not more than V1 Because the sum of vector is oppesite.
And the right side on the your sketch V should be more than V1 Because the vector are adding.
Your method testing should be matching with the transformer polarity check.
Thanks

Megger me kaise test karenge bataiye please

[@electricaldesifunda]

Megger is used to measure insulation condition of Motor and it is nothing to do with motor polarity test. If you want any technical help then email me at [e-mail]
