core balance current transformers (CBCT) 3 phase protection

[@harishnagapuri5471]

Super explanation sir tq so much plz do more like this with detailed explanation

[@mahendravishwakarma6940]

I like this video very good

[@subathradevi91288]

👌super sir, nice

[@scienceinnovativebrain]

Thankyou for your support

[@mmhshajib]

Informative video..thank u

[@RahulPatil-nm6vz]

Very well explained Anil Sir 👍

[@sandhyasharma72]

Awesome earth fault protection idea

[@kotreshayarahalli3120]

Nice explained sir

[@hatagof.auirab8528]

The explanation was on point and super easy to understand. thank you so much

[@jayshankarkumar8064]

Good knowledge

[@ayyappanr3149]

Thank you 💐 can you explain about phase sequence of transformer je

[@ajayyadav-xq7yv]

I have seen one secondary terminal (S1) of CBCT kept open, on asking it was found not in line. Module was in running condition. My question how it is safe and different from CT

[@scienceinnovativebrain]

May be that ct have some internel load impezance. You have to check datasheet of that ct.

Sir CBCT ki selection kis trah krty hain ?? jesy ham CT ki ratio ko dekh k lgaty hain.. Kia CBCT ka koi formula hai . Q k 1 CBCt har jaga to ni lga sakty koi 500A ka breaker koi 100 ka to kesy select kren CBCT ko

[@scienceinnovativebrain]

Ratio k according hi lgta hai but Jo bhi controller use karte hai usme ratio ka option aata hai.

[@sohailalvi5816]

@@scienceinnovativebrain koi formula k ratio nikalny ka.. 100A ka breaker hai to Kitni Ratio ki CBCT lgy gi any formula

[@scienceinnovativebrain]

100/5 amp

[@vijimurugan54]

our mccb(160A 4wire system ) is off position,load side isolater also off.but why ELR get trip.

[@scienceinnovativebrain]

How the elr ic connected and have to understand first ckt connections then only can tell something.

[@vijimurugan54]

load side isolater is off position and MCCB also off.but ELR get trip and showing 20A fault red indication

[@tapananilsamant2283]

Cbct has current rating?

[@scienceinnovativebrain]

All rating you will get

[@sreekanthch4397]

My load is 400 amps , what is the CT prymary rating

[@scienceinnovativebrain]

If CT through hole type and current carrying conductor is pass through CT then primary turn is 1 and secondary is depend on what out required as per primary current.

[@sreekanthch4397]

Sir, I mean that what is my CT Rating ( my load 400 amps) 400/5 or 500/5 if any calculation is there

[@scienceinnovativebrain]

You can choose any one accordingly in same ratio you have to select controller or display

[@velusamypothiraj2300]

If neutral wire 4wire how to connection made

[@scienceinnovativebrain]

I think you are asking for 4 wire system do not pass the neutral wire from CT only r y b you pass from CT

[@GSVOLGES]

Thanks For deeply explanation, But I have one doubt that In fault condition CBCT what is generate through a flux current or voltage which is use to operate the relay..?

[@scienceinnovativebrain]

It will generate current and that current transformers required some burden/ load by which current converter into voltage and Relay ckt will sense and trip circuits breaker

[@electricaltechie]

Will CBCT give tripping signal in Unbalance condition, in which no Earth fault has happened ???

[@scienceinnovativebrain]

Yes but may be it will depend on your controller setting how much % difference or unbalance set.

[@manasroutray5987]

Sir in 3 phase system voltages r separated by 120 dg

[@scienceinnovativebrain]

Yes 120 degree phase shift

[@monuvarshney2809]

Simple Formula I(f) = I (r) [cos0+jsin0] + I (y) [cos120+jsin120] + I (b) [cos240+jsin240] I was here only to know that if all the three phases are short to ground and current is flowing in same magnitude then what will be CT secondary output?

[@jayshankarkumar8064]

Sir 120 degree each

[@jaygatev9964]

❤️

[@n.gopalakrishnasarma8930]

well explained. thank you sir. please tell me why it is called ''core balanced'' CT.

[@scienceinnovativebrain]

Because in healty condition the total vector sum of the flux is balanced in the core any it operate when the unhealty condition occurred
