“…Electromagnetic fields attendant of a lightning current induce voltage in nearby structures, including houses, conductors, and underground cables. Magnitude of overvoltages is inversely proportional to the distance between points of stroke and location or structure housing LED devices [4]. At low system voltages (as is the case of luminaires and other LED-based devices), this may result in a few kilovolts (kV) with differential mode coupling (DM) and tens of kilovolts for common mode (CM) with consequent surge current in the region of tens of kilo amps for CM [2,4,5].…”

This chapter gives an extensive overview into the nature of the environment that luminaires and thus LEDs are subjected to during the event of a lightning stroke. Direct lightning stroke almost always results in instant damage for low-voltage connected devices, except in "extraordinary circumstances" where random components may survive. This is usually not a subject for debate and is not the subject of this monograph. Indirect consequences of lightning strokes, however, can be effectively mitigated as described. This chapter also delves into a realistic expected overvoltage levels for two typical systems, overhead lines and insulated cables, as obtained from lightning studies on a power network supplying power to LED devices and thus justifies the recommendations by several standards. In addition, it shows the importance of an often neglected device-MOV in mitigating attendant surges due to lightning to a level that can be withstood by LEDs and associated devices.

The effects of lightning strike to transmission and distribution systems are numerous and unfavorable. Just imagine the cost and havoc if a giant telecommunications company is shut down for an hour or day as a result of devices damage or a petrochemical plant catches fires due to lightning strike. Hence the needs to protect power apparatus from overvoltage surge are imperative. In this study an adaptive risk analysis & management (ARAM) based on artificial neural networks is proposed to analyze and proactively control the overvoltage at power substation due to lightning strike. General TermsMachine learning classification problem and System design.

“…The ground potential rise (GPR) is also generated by the lightning strike to the ground. The authors have proposed a simulation method for the overvoltages caused by the GPR [4,5]. V LIV and V GPR show opposite polarity.…”

This paper discusses flashover on a medium voltage line caused by nearby lightning. Simulations are carried out using analytical formulas for the lightning-induced voltage and the ground potential rise as a fundamental study. A flashover is determined using an integration method, which is a flashover model and can consider an influence of voltage waveform on the flashover. From the simulation results, the lightning overvoltages and the flashover on a medium voltage line are affected by the ground potential rise as the soil resistivity becomes higher.
