what will happen if the connections of protection ct reverse? will it burn the ct?..

Answer / sheikh

in case of reverse connection CT will not burn . however connected equipment may goes to malfunction or dead condition. as per example if Ct connected to kw meter and connection made inverse then kw meter given reading in Minus
like -245,-500kw . an other if ct work with any protection device like on reverse power relay in gen set and connection made in reverse then gen set goes on reverse power shutdown.
