This chapter begins with an introduction to concepts of energy, direct current (DC) power, and DC system efficiency. DC power and efficiency discussion sets the stage for the more complex concepts of single-phase alternating current (AC) power and AC energy. Discussion of single-phase AC serves as a suitable segue for consideration of the more complex subject of three-phase AC power. Power in direct current realm is equivalent to power in the mechanical realm, for most practical purposes. Conveyance of material through powered conveyors, aside from the selection and design of other pieces of equipment, requires sizing and specification of conveyor motors. The AC circuit depicts a simplified, single-phase, one-line diagram of a “special purpose” power generating station. The concept of efficiency, when applied in the electrical engineering domain, typically, involves power or energy. Hydraulic pummps, driven by electric motors, represent the exact converse of the hydroelectric power generating systems.
