Question

A 30 mva, 11.5kv, star -delta power transformer is to be protected by differential protection. The high voltage side face behind low voltage side phase by 30% formulate a complete differential protection for the transformer by selecting ct ratios,ct connections. The continues current capacity of restraining coil of the differential relay should not exceed 5 amp ct ratio is 3000/5 on 11.5 kv side. Determine ct ratio 69kv side

Answer 1

Dissipation is the result of an irreversible process that takes place in homogeneous thermodynamic systems. A dissipative process is a process in which energy is transformed from some initial form to some final form; the capacity of the final form to do mechanical work is less than that of the initial form.
