1) The Efficiency of the transformer depends on copper
loss and core loss, prepotional to the voltage & square
ampere.also power factor is depend on load. thats why
transformer is rated in KVA.
2) CT secondary is either connected with relay/ICT or it
will be shorted as it is working as step up voltage
(dangerously high) principle, cause human/equipment damage
PT is using as a voltage measurement and
protection,winding must be open or connected with load of
rated burden.
