Classification of Transmission Lines

Classification of Transmission Lines: Classification of Transmission Lines are usually classified as Lines with no loss or ideal lines, Lines without distortion or distortion less lines Lines with small losses, and Lines with infinite and finite length defined by all the four parameters. 1.Lines with no loss or ideal lines A line is said to […]

Characteristics of Lightning Strokes

Parameters and Characteristics of Lightning Strokes: The parameters and Characteristics of Lightning Strokes include the amplitude of the currents, the rate of rise, the probability distribution of the above, and the waveshapes of the lightning voltages and currents. Typical oscillograms of the lightning current and voltage waveshapes on a transmission line are shown in Figs

Lightning Stroke Definition

Lightning Stroke Definition | Mechanism of Lightning Strokes: Lightning Stroke Definition explains that when the electric field intensity at some point in the charge concentrated cloud exceeds the breakdown value of the moist ionized air (≈ 10 kV/cm), an electric streamer with plasma starts towards the ground with a velocity of about 1/10 times that

Simpson Theory of Lightning

Simpson Theory of Lightning: The factors that contribute to the formation or accumulation of charge in the clouds are too many and uncertain. But during thunderstorms, positive and negative charges become separated by the heavy air currents with ice crystals in the upper part and rain in the lower parts of the cloud. This charge
