What is an Electrical Insulator ?Definition of Electrical InsulatorAn electrical insulator is defined as a device used in electrical systems to prevent unwanted current flow to the earth, providing a very high resistance path.Insulating MaterialsInsulating materials must be strong, have high dielectric strength, high insulation resistance, be non-porous, and free from impurities.Properties of Insulating Material High mechanical strength High dielectric strength High insulation resistance The ins

What is Diversity Factor ?Diversity Factor DefinitionDiversity factor is defined as the ratio of the sum of maximum demands of individual loads to the simultaneous maximum demand of the system.Importance of Diversity FactorA high diversity factor means that a smaller electrical source can serve more loads, making it commercially viable.Peak Load TimingDifferent types of loads (domestic, commercial, industrial, etc.) have peak demands at different times, which helps in managing the overall load o

What is a Concrete Pole?Concrete Electric Pole DefinitionConcrete Electric Pole are used in 11 KV and 400/230 volt system to a large scale, apart from this, we also use Concrete Electric Pole in 33KV H.T. Line.Concrete Electric Pole AdvantageThe strength of the PCC Pole is much more than that of a wooden pole but less than that of a steel pole.Concrete Electric Pole Disadvantage Weighty BreakableConcrete Electric Pole Type R.C.C. Poles P.C.C. Poles

What is a Wooden Pole?Wooden PolesDefinitionWooden poles were widely used for 400 volts and 230 volts low tension (L.T.) lines and 11 K.V. high tension (H.T.) lines. Occasionally, they were used for 33 K.V. lines.Wooden Poles AdvantageWith proper maintenance and treatment, wooden poles can last a long time.Wooden Poles Classification The breakdown force is above 850 Kg/cm2. Examples are Shaal, Masua wood, etc. The breakdown force is between 630 Kg/cm2 and 850 Kg/cm2. Examples are Tik, Seishun, G

What is an Electric Pole?Electric Poles DefinitionElectric poles are structures used to support overhead power lines, ensuring the distribution of electricity.Types of Poles Wooden Concrete Steel tubular Rail polesWooden Pole TreatmentWooden poles need proper seasoning and chemical treatments to protect against moisture and termites.Concrete Pole FeaturesThese poles use reinforced cement and often include copper strips for earthing; they vary in height and load capacity.Electric Pole HeightThe h

What is Load Factor?Load Factor DefinitionLoad Factor is defined as the ratio of the average load to the maximum load over a specific period.Calculation MethodLoad Factor is calculated by dividing total energy consumption by the product of peak demand and time period.Efficiency IndicatorA high Load Factor indicates efficient energy use, while a low Load Factor suggests inefficiency.Impact of Peak LoadReducing peak load helps improve the Load Factor and reduces electricity costs.Load ManagementSh

What is Electron Emission?Electron Emission DefinitionElectron emission is the release of electrons from a material’s surface when they gain enough energy to overcome the surface barrier.Types of Electron EmissionThe main types are thermionic emission (heat), field emission (electric field), photoelectric emission (light), and secondary electron emission (high-energy particles).Work FunctionThe work function is the minimum energy needed for electrons to escape a material’s surface.Applications i
