Soil Resistivity Structure and Its Implication on the Pole Grid Resistance for Transmission Lines
High Voltage (HV) transmission lines are widely spread around residential places. They take all forms of shapes: concrete, steel, and timber poles. Earth grid always form part of the HV transmission structure, whereat soil resistivity value is one of the main inputs when it comes to determining the earth grid requirements. In this paper, the soil structure and its implication on the electrode r...
متن کاملElectromagnetic Radiation from Unbal- Anced Transmission Lines
A theory for the electromagnetic radiation from unbalanced transmission lines is developed. It is shown that radiation results from the convection current that develops in unbalanced transmission lines where the resistances of the lines are unequal. The process that leads to the generation of the nonlinear convection current in unbalanced transmission lines is explained. It is proved that the c...
متن کاملAdverse Effect of Electromagnetic Fields from Power Transmission Lines ( A Review )
31 Abstract—The electric and magnetic fields are originated by the alternating currents in the power transmission lines and known as electromagnetic fields (EMFs). The voltage is responsible for generating the electric field and the magnetic field produces by the current that flows in the transmission lines. Many epidemiologic studies in last decades focus on the effect of the continuous and oc...
متن کاملExposure to Electromagnetic Environment in Vicinity to Power Transmission Lines and Possible Health Effects: A Review
The possible relationship between human exposure to electromagnetic environment in the vicinity to high and extra high voltage (EHV) power transmission lines and their adverse health effects has become a subject to considerable public interest and concern. The preparation of this review have been carried out for the purpose of quantitative assessment of biological interaction and to evaluate th...
متن کامل1 . Reactive Power Compensation of Transmission Lines
1.1 General Introduction During the past two decades, the increase in electrical energy demand has presented higher requirements from the power industry. More power plants, substations, and transmission lines need to be constructed. However, the most commonly used devices in present power grid are the mechanically-controlled circuit breakers. The long switching periods and discrete operation ma...
