Q$1.$ A distribution transformer provides power for two feeders. Each feeder also feeds two laterals. The hourly load for the first feeder is given on the table. The coincidence factor for the second feeder is $0\mathrm{.}8.$ The daily maximum demands for these laterals are $1300$ kW and $1600$ kW $.$ Also, the average load of the transformer for a day is $3000$ kW and the load factor is $0\mathrm{.}75.$ By using the given data,

a$.$ What is the demand interval for the given system? $(5$ pts$.)$

b$.$ Find the diversity factor for the first feeder. $(7\mathrm{.}5$ pts $.)$

c$.$ Find the contribution factor of the lateral$-2$ for the second feeder. $(7\mathrm{.}5$ pts $)$

d$.$ Find the load diversity for the transformer. $(12\mathrm{.}5$ pts $)$

e$.$ Find the diversity factor of the transformer $(7\mathrm{.}5$ pts $.)$
