Question

Two transformers each serving four customers are shown in the Figure below: The following table gives the time interval and kVA demand of the four customer demands during the peak load period of the year. Assume a power factor of 0.9 lagging. 1. For each transformer determine the following: a) 30-minute maximum kVA demand b) Noncoincident maximum kVA demand c) Load factor d) Diversity factor e) Suggested transformer rating (50, 75, 100, 167) f) Utilization factor g) Energy (kWh) during the 4-hour period 2. Determine the maximum diversified 30-minute kVA demand at the Tap
