CT operating in normal mode then fault current appears in load ... how can we reduce fault current on primary side by effective changes on Secondary side... what are the changes possible on Secondary side to reduce fault current on primary side

[@Ragavenutb]

Hi,if data markings on the CT's disappear how would one determine the correct ratio? Thank You.

[@electricallectures]

Then you have to do it by hit and trial. One thing for sure the output is always 5. So by measuring secondary current and primary you can compute ratio

[@Ragavenutb]

@@electricallectures so i basically run 100a through the line and measure Ct output amps. If its 2.5 its primary is 200a. But due to impedance and accuracy class, output can't be accurate right?

[@Artistic_S0ul_]

I have a question. Please could you tell me, what would happen if the flow primary current is 300 A permanently, and the ratio CT is only 200/5 A? Thanks by the answer.

[@electricallectures]

Ct will saturate and 5 A will continue to flow

[@Artistic_S0ul_]

@@electricallectures Thanks a lot by the answer.

[@fabianm.2982]

@@electricallectures I don't agree, please elaborate further. There are times when you can set the pick to be above the 100% rating, which is 5A. I have seen the CT's rated 600/5A and relay set at 1.2 of the primary current. Is that a wrong practice or what?

[@electricallectures]

Absolutely wrong. Ct can only produce 5A. As far as pickup is concerned , 1.2 can be set if the maximum primary current is 600. Let say ur relay is supposed to trip @400A which is 1.2 times. Now ur ct is 600/5 and it will work in this situation

[@suryasreedharreddy2277]

What happens on primary side current when burden increases on Secondary side

[@electricallectures]

No effect on primary but if burden exveed the ratio will be disturbed and so as secondary current

[@suryasreedharreddy2277]

If the Secondary winding is replaced with reactance instead of short circuit after sometime then what happens on primary side current

[@debarpanchanda7506]

Sir could you please explain any practical application or uses of reduction of CTR...? It's will be much beneficial for me..Thanks in advance sir.. 🙏🙏🙏

[@electricallectures]

Do you want to ask usage of CT . I dont actually understand your question. Reduction of ctr

[@user-uf5wg7ex2i]

200/2 farmola 😊

[@electricallectures]

Don't understand

[@michelvidallo7288]

i cannot understand you bus or bar type?? wtf
