Steady-state Solutions in an Algebra of Generalized Functions: Lightning, Lightning Rods and Superconductivity
نویسنده
چکیده
Formulas for the solutions of initial value problems for ordinary differential equations with singular δ-like driving terms are derived in the framework of an algebra of generalized functions (of Colombeau type) over a field of generalized scalars. Some of the solutions might have physical meaning such as of the electrical current after lightning or under superconductivity but do not have counterparts in the theory of Schwartz distributions. What is somewhat unusual (compared with other similar works) is the involvement of infinitely large constants, such as δ(0), in some of the formulas for the solutions.

Closed-Form Solutions for Broad-Band Equivalent Circuit of Vertical Rod Buried in Lossy Grounds Subjected to Lightning Strokes
Abstract— In this paper, input impedance of a vertical rod under lightning stroke is first computed by applying the method of moments (MoM) on the Maxwell’s equations. The circuit model is then achieved through applying modified vector fitting (MVF) on the computed input impedance. After then the equivalent circuit is again extracted for a few values of soil conductivity and rod radius. Finally...
متن کاملOne case of a lightning strike leads to death: case report
Background: Lightning is one of the most mysterious phenomena of nature that also, it has caused many financial and human losses. In tropical and sub-tropical countries, death due to thunderbolt is not unusual, and even tragic events may occur at high altitudes. Lightning physics is complex and not completely clear. Usually, the clouds are heavily pregnant and high voltages and amperages, they ...
متن کاملAn Algorithm to Nowcast Lightning Initiation and Cessation in Real-time
Cloud-to-ground lightning data from the National Lightning Data Network (NLDN), satellite visible and radar-derived products are used to train a lightning prediction algorithm. The radar reflectivity values are clustered to identify storm and real-time geometric, lagrangian and scalar attributes of those storms are computed. A lightning density field is ”precast” to form the target decision fie...
متن کاملImpact of Ocean-Land Mixed Propagation Path on Equivalent Circuit of Grounding Rods
In this paper, the effect of ocean-land mixed propagation path on the lightning performance of grounding rods is investigated. This effect is focused on two problems. The first is extracting exact equivalent circuit of grounding rods in the presence of oceans. The equivalent circuit can be used in transient analysis of power systems in the neighboring oceans. In the second one, this effect on t...
متن کاملStudy on the Effectiveness of Single Lightning Rods by a Fractal Approach
Lightning rod is widely used in lightning protection systems. It is of practical interest to analyze the protective performance of a lightning rod taking into consideration some stochastic behaviors of the lightning process. The effectiveness of a single lightning rod is investigated in this paper using a fractal growth approach based on dielectric breakdwon model (DBM). The effective intercept...
