WHAT SHOULD BE THE BEST CURRENT RATINGS (PRIMARY / SECONDARY)FOR A CT INSTALLED AT THE INCOMING 11KV PANE? WILL IT BE CALCULATED ON THE BASES OF MAXIMUM DEMANT VALUE OR ON SUM OF ALL TRANSFORMER'S KVA? NOMALLY MAX DEMAND REPRESENT THE MAXIMUM OPERATING LOAD OF THE PLANT AND TOTAL KVA OF (SAY 5 NUMBERS TRANSFORMERS) REPRESENT THE CONNECTED LOAD. WHICH i.e. MAX DEMAND KVA OR CONNECTED KVA ARE BETTER TO USE FOR CT CURRENT CALCULATION? PLEASE ANSWER.
