Answer Posted / rites
CTs are used for in the measurement of current as a primary
sensor. The output of the CT is connected to the relevant
power meter. For CT the primary is the busbar / cable
caarying current which generates current in the secondary
by induction. Now if CT secondary is kept open and current
flows through primary the induced emf in the secondary will
not have a close path to flow which will lead to opening /
bursting of the CT.
