Electrical Power Systems

Explore the seven configurations of electrical generation plants, outlining fossil, hydro, nuclear, solar, wind, and gas turbine options, their capacities, and energy efficiency considerations.

Describes power and distribution transformers in substations that raise voltage for transmission and reduce it. Covers insulation media such as air, oil, and sf6 gas up to 500 kilovolts.

Describe how transmission lines move power from generation to substations using high voltage, classify lines by length (short, medium, long) and voltage levels (low to extra high), noting insulators.

Explore distribution lines as medium voltage conductors that transfer power from generation to cities, using step-up and step-down transformers to convert generation voltage to transmission and 400-volt consumer voltage.

Explore electrical loads by category: static (resistive) loads such as heaters and fluorescent lamps, and dynamic loads like induction motors that rotate continuously.

Explore switchgear in the protection system, showing how the board is supplied from generation and distributed to subscribers, and how circuit breakers, fuses, and transformers ensure safe protection.

Explore component 7 equipment for improving electrical power system performance, including capacitors for power factor improvement and energy quality, reducing losses and increasing line capacity.

Explore electrical energy and kilowatt hours, dc and ac circuit behavior, and single- and three-phase power, including active, reactive, and apparent power and power factor.

Analyze resistive, inductive, and capacitive loads, covering active and reactive power, power factor, and how voltage and current relate: in phase for resistive, lag for inductive, and lead for capacitive.
