we have two 11/.433 kv. distribution Transformer rating as
1000 kva & 500 kva , i wants to run parallel both transformer.
both transformer impendence voltage is 5.24%, How can we run
both t/f, & how sharing the load

Answer Posted / kandasamy

Since both the trasformers are identical impedance , The
load sharing will be exactl equal OF TOTAL (LOAD)POWER.
Load sharing of transformer A= Power x(ZB/ZA+ZB).
Load sharing of transformer B= Power x(ZA/ZA+ZB).

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.
