Answer Posted / rajesh dhankar
i'm sorry to say that above two answer give above are half
correct. because all u r talking about ionized air if u ever
open Chamber where CT's and PT's are connected u will find
distance less than a hand away and there is no problem of
ionized air there.
The main reason after that is at a time of breaking a ckt or
can say shutting down a ckt when load is not completely zero
there can be big damage or accident because of higher
voltage rather if load is completely zero then there is no
problem.
and ACB are used in low tension line where low voltage and
higher load can be controlled.
