these are instrument transformer, in which c.t is current
tranformer who measure the current in each phase in a ratio
according to rating of c.t and we can called c.t such as
step up transformer.it installed in series of line.
P.T is a potential t/f who measure the voltage b/w two line
in a ratio according to rating of p.t and we can called p.t
such as step down transformer.it installed in accros of line
