@sankujyotisarma3974 2 года назад

Thanks sir...very good explanation. So if i am to select a fuse to run a 100kva load so i i will have to convert 100 kva into kw i.e 125 kw then to watt i.e 125000w then {125000÷(1.732×415)}×1.25=217.382. So i can use a 250A HRC fuse. Please tell me if i am right or wrong.

@sid-cm1eg 2 года назад

what about power factor, i guess we need to multiply power factor in denominator for 3 phase

@jitendraverma7373 Год назад

Dear Abhishek ji Mostly we seen relay manual back up fuse rating given three time of motor kw.but as per your three phase motor calculation fuse rating app. equal to full load of motor current.so we confuse here.so pl help to explain it. Thanks

@RockingSM 3 года назад

Sir, what about overload? If 2 times rated current is to flow through this fuse for 10 sec, then how to confirm whether selected fuse is OK for such applications?

@nadim606 8 месяцев назад

By which formula will you choose the circuit breaker? Thanks

@nileshparmar1918 3 года назад

Hii Abhisek You explain very well..and you make really interesting and knowledgeable videos, i really appreciate for that.. But I like to clear one think.. NO stand for Normally Open NC for Normally Close in normal condition it means when circuit is not in use.. But when you start the circuit NO contact become CLOSE not NC and NC contact become OPEN not NO Thank you..

@wasim3617 4 года назад

Abhishek bhai ...thanks for good video I have a query how to select hardware for DCS marshaling panel like ACto DC power supply, TB rating , fuse rating ,barrier , fuses

@electricalwithabhishekjoshi 4 года назад

Hello Wasim. For DCS related query, I need to consult with my seniors as I don't want to give any false statement.

@anoop22march 4 года назад

Sir , can we consider Power factor for this calculation

@electricalwithabhishekjoshi 4 года назад

Hello Alok, I have referred two books for this Calculation. It is same as mentioned in this video.

Sir ham 1.5 nhi use kr sakte kya

@MuhammadSaeed-wr7nt 2 года назад

Sir AP ny formula my pf our effiency add nai ki na single phase ma na Three phase ma

@rahulji245 4 года назад

I want to know to use rating of semiconducting fuse in case of Dc motors

@electricalwithabhishekjoshi 4 года назад

Okay Rahul 👍

@SaurabhSingh-ui8jh 3 года назад

Jab three phase me agar hum 420 volt suppose le rhe hai to phir √3 se multiply q krna hai ?? Agar 420 * √3 ke denge to ye karib 726 volt ho jayega to us hisab se hamara 3 phase ka voltage 726 consider ho jayega 🤔🤔🤔🤔🤔

@kumardada3691 2 года назад

In DC?

@gsmusiccafe6145 4 года назад

Hi Abhishek, Please tell me the fuse selection guidance for 100V DC voltage and use of ampere squared time factor

@gsmusiccafe6145 4 года назад

Plz reply

@electricalwithabhishekjoshi 4 года назад

Hello, I don't know its exact ans. So I don't want to give any false guidance.

@jagdishchaudhary8429 3 года назад

Please give the derivation for safety factor as I am not able to get it any where.

@kiranjadhav7258 3 года назад

Sir manlo motor 46amp he to kitne ka fuse lagega Waise 10/less than current fix krte he lekin Mere kahne ka matlB ye he ki Fuse ki reting to pahle hi fix hoti he Or aa rahe mil rahe amp se Reting fuse kam rakhe ya jyada rakhe ....?Pls reply mi

@electricalwithabhishekjoshi 3 года назад

Kiran, video mein bataya gaya rule aap yaha bhi apply kar sakte hau.

Sir Hamara company ni me ek agitator Moto 55 kW ka he to is formula se 96A ho Raha he Lekin feeder me 200 A ka fuse Laga he .to sir please explain the query please

@electricalwithabhishekjoshi 4 года назад

Shibaprasad, 55kw ka FLC is 110A. But bcoz of high Starting current, 200A is good. But 200 se ek range kam ka bhi laga sakte ho koi problem nahi hai..

@amittiwari6399 26 дней назад

Sirji.....my fuse rating is not matching with this formula as motor is of 2.2 kW & fuses in feeder are of around 16/20 A....but by this formula it's calculating just around to 4 A

@pramitapsatapathy5037 3 года назад

Sir If we are using Relay for protection then what is the need of using Fuse ?? Kindly answer .

@electricalwithabhishekjoshi 3 года назад

They are used as a backup protection to protect motor.

@pramitapsatapathy5037 3 года назад

@@electricalwithabhishekjoshi that means when relay fails to operate due to malfunctioning then Fuse helps in protecting the circuit ??

Sir aik 160 kva ka Dg hai jo R 70ams Y 80ams B 90ams Load hai to total kitna amps load Dg pe run kr rha hai sir kese nikale please help me sir 🙏🙏🙌

@electricalwithabhishekjoshi 4 года назад

Vivek ji, Aisa nahi sochna ki hume in current ko plus karna padega.. aisa nahi hai.. Agar aapko resultant current chahiye to aap simple iska average nikal sakte hai..

@electricalwithabhishekjoshi 4 года назад

Ye DG hai isliye load unbalance hai. Isliye average nikal ke hum resultant current nikal sakte hai..
