The following given set of data shows a set of 15-minute kWdemands for four customers over a 24-hour period. A 25kVAsingle-phase transformer serves all the customers.
(a) Find the maximum 15-minute demand for each customer and theaverage 15-minute demand for each customer
(b) Find the total kWh usage and the load factor for eachcustomer.
(c) For the 25kVA transformer, compute the maximum 15-minutecoincident demand, the maximum 15-minute non-coincident demand andthe load diversity.
