Draw the single-phase diagram for the entire electric system.
A small factory is supplied by a three-phase 380V 60 Hz power source. It has three electrical equipment with the connections as shown in Figure 1.
Water Pump
Electric Motor
Capacitor Bank
380V
Source
Plant Loads
The specifications of each of the equipment are listed as follows:
A 25.5 kW electric water pump with a power factor of 0.85 lagging.
An electric motor with a rated current of 30 A and a power factor of 70% lagging.
A capacitor bank with a reactive power of 24 kVAR.
Assume all loads are three-phase Y-connected balanced loads.
