High Voltage Test on Circuit Breaker and Isolators: High Voltage Test on Circuit Breaker and Isolators is covered, giving common characteristics for both. While these characteristics are directly relevant to…
Insulation Coordination of Substation: For steep fronted lightning waves at Insulation Coordination of Substation and at different points on lines, the voltages at sub-stations may exceed the protective level depending…
Attenuation and  Distortion of Travelling Waves: As a Travelling Waves moves along a line, it suffers both attenuation and distortion. The decrease in the magnitude of the wave as it…
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,…
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…
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…
Cascade Transformer Connection: Figure 6.10 shows the Cascade Transformer Connection units in which the first transformer is at the ground potential along with its tank. The second transformer is kept…
