“…However, care must be taken to average only sferics that are known to have originated from a small geographic location so that the propagation effects on their spectrum are identical. The National Lightning Detection Network (NLDN) provides the location and time of an individual discharge to an accuracy of a few kilometers and better than 1 ms [Bernstein et al, 1996], which allows the unique identification of the source location of an individual sferic (which also must be known to accurately model the sferic propagation). To produce an average sferic spectrum, we average the sferics determined by the NLDN to have originated in a 0.5 ø latitude by 0.5 ø longitude region (•56 km by 48 km at latitudes of the continental United States).…”

“…In 1979, the Tampa Electric Company began using real-time lightning maps to monitor the approach of lightning storms, estimate their severity, and then preposition, hold over, or call out repair crews as necessary [63]. Today, more than 80 electric power utilities in the United States use real-time NLDN data in a similar fashion in their daily operations [64]- [67], and in conjunction with EPRI's Lightning Protection Design Workstation [68].…”

Lightning is a significant cause of interruptions or damage in almost every electrical or electronic system that is exposed to thunderstorms. The problem is particularly severe for electric power utilities that have exposed assets covering large areas. Here, we summarize the basic properties of cloudto-ground (CG) lightning, the primary hazard to structures on the ground, and then we discuss methods of detecting and locating such discharges. We describe the U.S. National Lightning Detection Network TM (NLDN), a system that senses the electromagnetic fields that are radiated by individual return strokes in CG flashes. This network provides data on the time of such strokes, their location and polarity and an estimate of the peak current. We discuss the network detection efficiency and location accuracy and some of the limitations that are inherent in any detection system that operates with a finite number of sensors with fixed trigger thresholds. We also discuss how NLDN data have benefited utilities by providing lightning warnings in real time and information on whether CG strokes are the cause of faults, documenting the response of fixed assets that are exposed to lightning, and quantifying the effectiveness of lightning protection systems. We conclude with some general observations on the use of lightning data by power utilities and we provide some guidelines on the uncertainties in lightning parameters that are acceptable in the industry.

“…Today, the modern LLS are increasingly used by power and distribution operators. Application in transmission and distribution networks and systems is mostly encountered in one or more of the following areas: a) in correlation of outages and faults in network with lightning strokes; b) in establishing, managing and monitoring of electric power system; c) in giving a warning of coming lightning front; d) in choosing the route of overhead lines and ways to protect them from lightning, [1][2][3][4][5].…”

Lightning location systems (LLS) provide data on lightning activity such as lightning type, GPS location, exact time of the lightning stroke, lightning current amplitude, measurement error, etc. The proper application of LLS data using customized software support can be a powerful decision-making tool in the control, maintenance and development of power systems. The utilization of lightning data in power systems requires a customized software support with specific functionalities. Software functionalities include real time lightning activity visualization with alarm function; analysis, reports and historical lightning activity visualization; spatial correlation between lightning data and alarm zones around geographically represented power system’s objects (power lines, power facilities, etc.); calculation of lightning statistics; generation of wide area lightning density maps, generation of high resolution lightning density maps inspecting alarm zones around the power lines; real time correlation between lightning activity and the power system protection equipment (distant protection relays), gathered through the SCADA system. In this paper, emphasis will be given to the application in correlation between faults and outages in the power network and lightning strokes. Today, many power companies monitor data related to circuit breaker operation or reclosing using various equipment. Such equipment allows online monitoring of circuit breakers and alarm statuses of equipment in substations.
