Question
An ideal transformer is rated to deliver 460 kVA at
380 V to a customer, as shown in Figure.
a. How much current can the transformer supply to
the customer?
b. If the customer’s load is purely resistive (i.e., if
pf = 1), what is the maximum power that the
customer can receive?
c. If the customer’s power factor is 0.8 (lagging),
what is the maximum usable power the customer
can receive?
d. What is the maximum power if the pf is 0.7
(lagging)?
e. If the customer requires 300 kW to operate, what is
the minimum power factor with the given size
transformer?
