    Very informative,
    let me add a few points , usually power = voltage x current ( ideal conditions, no losses )
    Suppose a loco needs 30kw power from the OHE to run ,
    So a setting can be like , 30000w = 1000v x 30amp ,
    Now 30 amp current is a big thing and will heat up the OHE cable big time.
    now there is a property of A/c current that it can raise the voltage to lower the current passing through , yet keeping the same power output
    So using transformers to up the voltage ,
    above equation can be changed to 30000w = 10000v x 3 amp
    So with 25kv ie 25000v, the corresponding current would be around 1.2amp or so
    So now voltage is high and current in the cable is less, ie less heating of cable and yet same power is transmitted from the OHE cable to the loco.
    Off course this is all under ideal conditions and usually there is an additional component called Power factor which comes into play with ac currents.

      KW=KVA×POWER FACTOR
      =25× 0.8
      =20 KW

    very clear video.. I'm a civil engineer.. but I'm doing work in OHE field so did not know anything about OHE or locomotive... but by your video nd some other videos I'can able to learn everything easily and work perfectly...
    so thank you so much for your supporting videos. 🙂

    चैनल के बहुत सारे videos काफी informative है। मुझे इस चैनल के videos कुछ खास ही पसंद हैं। इसका मुख्य कारण यह है कि सारे videos 5 min से काम अंतराल या 5 min आस पास के होते है। आप इस तरह के और वीडियो बनते रहिये। वीडियो के लिए धन्यवाद।

    Bhai your videos are very informative and interesting. Please don't think about dislikes and Negative comments. Just concentrate on your work, here 50% comments are baised. Most of them are here to pick incorrect things, minor mistakes just to pretend they are damn smart. Just concentrate in what you are best...try to provide 1080 or above quality videos. Subject should match with the quality.

    DC Series motor can also operate on AC. Another advantage of increasing voltage and that too in AC system is that the weight of conductor per km decreases highly.
    Induction motors are also suitable because these motor can operate at constant speed and also at increased speed with reduced Torque. DC series motor has good Torque profile but speed drops drastically with load.
    By the way good video.
