what is the CT of protection and CT of metering ? what is
class 5P10 & 5P20 and class PS ?
Answer Posted / syed naveed akhter
ct can use as protuction in supply lines where 3 phase use
in different areas saperatly for example in lighting in
hall, if current pass throw one phase high then ct detect
emf out side the wite and generate some supply to cut the
main source.
as you know that ct is current transformer, it fix around
the wire where current flow. when load take some current
then out side of wite some emf produce which detect by ct
and its pass some voltage which use to measure (it is a
calculation which i dont know) help to metering.
