what is difference between 5A and 100A CT constructional wise
and operation?
Answer Posted / sudhakar.g
Depending upon its class and calibaration we use the CT's
of 5A and 100A....Genrally if we use on LTside we can use
5A and its class...for 100A it genrally prefer on HT side
like HT panels, Metering cubicles......why we are using CT
because how much Current we are consuming and it placed on
Outgoing cable of Incoming breaker....CT's outgoing we can
use the control wiing like LOAD manager, Relays because
those equipments want low voltages...
If u have any queries pls contact me
