Sentence examples for lightning grounding system from inspiring English sources

In this paper, the impact of neglecting these characteristics on a tall-mast lightning grounding system design is discussed.

Characteristics such as the frequency dependence of soil parameters, inductances and capacitances due to nearby metallic elements, and the actual geometry of the structure and its grounding system are commonly neglected or simplified in lightning grounding system design.

The ATP-EMTP circuit model of the OHL includes detailed line insulation and lightning representation; grounding systems are simulated by a new and simplified model which reproduces the effects of propagation along the ground conductors and soil ionization phenomena.

The study is focused on the step, contact and transferred potentials generated by a lightning striking a grounding system and the produced potential gradients that a person could be exposed to.

It is also concluded that, in addition to the lightning overvoltages, the unavailability of the TLs is significantly affected by wide-band model of grounding system, non-vertical lightning strokes and soil resistivity.

The proposed approach is applied on high voltage transmission lines in order to calculate the lightning outages, on grounding systems in order to assess the grounding resistance and on high voltage transmission lines' polluted insulators in order to estimate the critical flashover voltage.

Many buildings constrain the path of lightning currents and voltages through use of lightning rods, or air terminals, and conductors that route the current down into a grounding system.

The results provide useful information for the design and the behavior of a grounding system, encased either in bentonite or in conductive concrete under lightning impulse currents, as well as for the protection measures of installations from lightning strokes.

The grounding system is an effective parameter on the magnitude of the lightning overvoltages and insulation coordination of high voltage transmission lines (TLs).

As a result, it was indicated that the direct lightning to the elevated bridge over the substation caused the transient overvoltage of the grounding system of the substation and resulted in the breakdown within the rectifier.
