Can I use measuring current transformers in protection
purposes?
Answer Posted / minu
Mr. Mohit,
i am working as a power system protection engineer in one
of India's biggest consultancy firms. wat u said abt
increasing the no. of cores of a ct does not mean that the
metering n protection cts are same. n i think u've
forgotten ur basic engineering study wherein we were taught
abt the basic differences in metering and protection cts. u
can still find them in any gud power system book.
p.s. its Miss Minu, not Mr. Minu

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?

If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
