CT SIZING CALCULATION| How to select CT ratio| CT parameters selection

[@nik93393]

You have ability to threshold the remembering power of your students and stand them among the toppers grade!! Congratulations 🙏🙏

[@md.abdullatif6544]

Now I understand about ct ratio. Excellent

[@trilochan9152]

Great Video. You have skill of explaining in such a type that it will be forever in mind.

[@abhineshk.a609]

Dear sir thanks for your CT sizing calculation video. Your way of explanation is very simple and can understant easily. If possible please include the burden selection(VA) related to CT in your next video with the selection of wire resistance,size,relay burden details etc.

[@MegaPartyVan]

Your videos are amazing, I'm going to binge watch your whole channel.

[@adnansworld744]

Min, Knee point voltage is essential for 5P10 or IDMT protection CTs as per standard. Any conversion table available for Knee point voltage to ALF or Vice versa. Any can answer please....

[@himanshu2232]

Sir जब भी vedio लाते हो,धांसू ही लाते हो,और knowledge से भरपूर👍👍👍 प्लीज एक vedio PT के सिलेक्शन पर भी लाएं।

[@electricaltechnologyandind5335]

Sure....

[@Hemanth2787]

How the fault current will be dedect if the primary current is 100/1 ratio.. 100 ams is the max current knw

[@ashokkumarjangir5324]

Sir pls explain the line ct ratio when a bus bar connected to a two different transformer (AMT+TT) power will be 40MVA both and voltage 110kv/33kV for AMT and 110kV/27.5kV for TT. 🙏

[@ktsmurthy21]

Sir, Good Explanation. That means In case of Fault , Metering CT will fail.

[@electricaltechnologyandind5335]

Will be short circuited to protect the meter

[@ktsmurthy21]

Can you Explain How It will Short Circuit.

[@pratapjadhav]

Hii sir Which bases we considering on CT sizing and 20% margin spare ? Which Standard IS/IES We are studied?

[@TheMohlamonyane]

I have the same question. In other projects I worked they used 60% margin and I couldn't figure out why.

[@hariharan4674]

Thanks sir, I got better clarity once again thanks

[@patakotisrinivas1918]

Good explanation sir...

[@pritamchakrabarty3891]

Nicely explained... One doubt is there... Is PS class CT is same as protection class CT like 5P20?

[@varimas]

Sir. Great explanation. May i please request a lecture video on lightning protection, its method, techniques and calculations. Thank you.

[@elxanmusabayev1533]

Hello if 3200/5 CT with 5P20 class, means that 20x3200=64000x5%=3200A maximum error - is that correct?

[@electricaltechnologyandind5335]

Upto 20 times of rated current the error shall be with in 5%. Yes if 64000 A flows error can be upto 3200A.

[@krishnam4844]

Sir great explanation. Plz give information about Types of CTs and PTs available in the market.

[@manojkumarmahto9805]

Hello sir, really well explained in simple way. Please also make video on dual CT ratio selection

[@gustavomarcelo7250]

Hi. Means that we will have two CT of : 1. 3200/1,5P20 2. 3200/1 ?

[@electricaltechnologyandind5335]

Actually two core...... Yes.. correct

[@sajisivan]

great vedio ...thanks a lot

[@surendrakverma555]

Very good.

[@balasubramanian599]

What is rule for the core size selection

[@jaydhokai8364]

Thanks for Video.

[@birdeyeview3901]

Great Video Bro👍

[@balrajsubash282]

Hi For 5P20 class the fault current more than 20 times what will be the error on secondary side?

[@purnasahoo791]

Sir, Ty so much. It very helpful for me. Sir plz make a video about earth fault protection and it calculation.

[@electricaltechnologyandind5335]

Already there

[@purnasahoo791]

But it was about restricted earth fault but i say about motor earth fault current calculation.plzz

[@milanmukherjee9425]

Great sir.please make a video on NPS relay,and it's setting calculation.please

[@deepalps]

Thanks a lot for valuable information Kindly give transformer winding details for eg 440/110V 15VA

[@suresh.kmuthu7644]

Hi. Thnks for the video.one more request pls explain how to choosen the CT VA rating for protection & metering.

[@elxanmusabayev4930]

Why you have been using 0.433 kV when calculated CT ratio, but 433 V when you calculated transform current?

[@electricaltechnologyandind5335]

Trafo current is based on 433 V. Load currents are based on 415V. 433V and0. 433 kV are same i believe

[@sabarinarayanan4357]

Put videos about vfd and vsd

[@rukmagoud]

Sir u just informed PS class . You didn't explain about knee point voltage and formulas

[@electricaltechnologyandind5335]

It is available in my restricted Earth fault protection vides

[@mazharalibarodawala6999]

How to calculate burden of CT??

[@mdtarique6305]

Manufacturer wll provide how to calculate , ( data provided)

[@balakrishmam]

Great video 👍. One small suggestion. Always we are not getting bell icon button in the videos. Please include from next video. Thanks.

[@electricaltechnologyandind5335]

Press the subscribe button. Then you will get the bell icon. I don't do any thing else to create subscribe links. So you won't find it in my videos. Your love ia everything.....

[@balakrishmam]

I have already subscribed and pressed the bell icons also. Don't know why I can't receive the eye buttons link. However thanks for the reply.

[@udayakumar5379]

Hello sir, can you given me the explanation of how did you identity 5% or 10% error..?

[@electricaltechnologyandind5335]

That is a part of ct design. I haven't explained ct design here....

[@sudhansusamal8886]

2000 where came sir please answer

[@itsickdar7844]

perfect

[@balasubramanian599]

How to select the core size

[@electricaltechnologyandind5335]

That is for CT manufacturer

[@patelkaushik2996]

SIR APKA VIDEO BAHUT A6A HE LEKIN AAP HINDIME BHEJONA

[@syedmohammadsaif8344]

Better Explain from basic ,no matter video long

[@electricaltechnologyandind5335]

But i usually explain general industrial practice. Not basic..... Hope you will understand....

[@amargaikwad3151]

In short explain a lot
