ELECTRICAL SYSTEM1 Bureau of Energy EfficiencySyllabusElectrical SYSTEM :Electricity billing, ELECTRICAL load management and maximum demandcontrol, Power factor improvement and its benefit, Selection and location of capacitors,Performance assessment of PF capacitors, Distribution and transformer Introduction to Electric Power Supply SystemsElectric power supply SYSTEM in a country comprises of generating units that produce electric-ity; high voltage transmission lines that transport electricity over long distances; distributionlines that deliver the electricity to consumers; substations that connect the pieces to each other;and energy control centers to coordinate the operation of the components. The Figure shows a simple electric supply SYSTEM with transmission and distributionnetwork and linkages from electricity sources to Typical Electric Power Supply SystemsPower Generation PlantThe fossil fuels such as coal, oil and natural gas, nuclear energy, and falling water (hydel) arecommonly used energy sources in the power generating plant.

High voltage transmission is used so that smaller, more economical wire sizes can be employed to carry the lower current and to reduce losses. Sub-stations, containing step-down
