Application of Preventive Measures in Lightning Protection (original) (raw)

Theoretical framework of preventive lightning protection

Recently a new approach has been introduced in lightning protection, namely the preventive lightning protection. This lightning protection method differs from primary and secondary lightning protection in many aspects. The goal of each of these protection methods is the protection of human lives, material goods and cultural heritage from the effects of lightning. Primary and secondary lightning protection is based on the use of different devices. These devices are installed to the object to be protected, and protect it until dismantling them. In this aspect primary and secondary lightning protection are static lightning protection methods. Preventive lightning protection however is based on the usage of different preventive actions. These actions are executed only before lightning hazard develops, and are suspended after the lightning hazard passes. In this regard preventive lightning protection is a dynamic method. The paper describes the theoretical framework of preventive lightni...

Planning and evaluation of preventive lightning protection

Recent work in lightning protection has shown a new method solving existing problems in primary and secondary lightning protection. These are the direct protection of human lives, and some cost effectiveness issues. The new method giving a practical solution to these questions is preventive lightning protection. Preventive lightning protection is a protection method based on the application of preventive measures for the time of the thunderstorm, when lightning hazard exists.

A Review of Lightning Protection System - Risk Assessment and Application

Indonesian Journal of Electrical Engineering and Computer Science

A lightning strike could bring thousands mega-ampere of current in a blink of eyes. As a result, a failure of grounding the strike may cause serious damage to the home and industrial appliances and gadgets. Hence, a lightning protection system is essential to the current transmission system. Lighting is a natural phenomenon that is unavoidable. Hence, the study of the properties and characteristics of lightning is a must in designing lighting protection system. Every application has different criteria to be fulfilled. The type of lighting protection system is categorized based on the location and user. The different of location is a public area, transportation system, power system transmission and generation system which include renewable energy source. Each area can conclude different level of protection. This paper is assessing the possibility and probability of transient impact on all applications including, public area, power system line, and generating system. The review includes countermeasure which addressed few steps to determine the effect of lightning and countermeasure of protection.

Experimental analysis of preventive lightning protection methods

2014 International Conference on Lightning Protection (ICLP), 2014

In recent decades lightning detection technologies and computation methods have been developing in an unprecedented pace. Present-day observations from lightning location systems (LLS) allow real-time lightning hazard forecasting and provide as such the building blocks for novel and preventive approaches to lightning protection. Preventive lightning protection, a lightning protection method based on lightning hazard forecasting in combination with preventive actions, has been introduced in the literature. This paper approaches preventive lightning protection from a practical aspect by analyzing the efficiency of two forecasting methods: zonal preventive lightning protection and high reliability lightning protection. The analysis is carried out on archived lightning location data and a detailed comparison is given on the efficiency of these methods and their applicability with respect to the international standard.

Importance of Forecasting in Preventive Lightning Protection

In recent studies a new approach has been introduced namely preventive lightning protection. This is a dynamic method compared to the currently used primary and secondary lightning protection. The new method is dynamic both in time and space. Dynamic in this case means that the protection is in effect only during thunderstorms in a special area below the cloud. However to recognize the need for the preventive action, the thunderstorm activity has to be monitored in an area around the object to be protected. In this paper calculation methods of the usage of different types of forecasting are presented. Calculation is based on risk assesment taking into account the different parameters of the lightning detection systems. Based on existing data in the field different performace aspects of different systems are shown and their impact on the efficiency of preventive lightning protection is proved.

Issues of risk in non-permanent lightning protection methods

The use of non-permanent protection methods has emerged in lightning protection in the last decade. The theory of using such methods were introduced to lightning protection as the so-called preventive lightning protection referring to the fact that this method uses preventive actions as a method of protection. These methods fundamentally differ from the primary or secondary lightning protection methods, as the protection itself is realized by a temporary method, executing (one or more) preventive actions. This fundamentally different functionality requires a completely different approach in terms of risk management as well.

Reduction of NaTech Risk Due to Lightning by the Use of Protection Systems

Several accidents that occurred in the last decades evidenced that the impact of natural events in industrial plants may trigger accidental scenarios involving the release of relevant quantities of hazardous substances. Severe scenarios typical of the process industry, as fires, explosions, toxic releases, and water pollution were reported as the consequence of natural events in industrial areas. The specific features of technological accidents triggered by natural events were recently recognized, and these scenarios are now indicated as NaTech (natural-technological) accidents. The screening of past accident databases points out that NaTech scenarios are quite common in industrial facilities. Past accident analysis evidences that lightning is one of the most common initiator event for fires in oil refineries and tank farms. In most facilities, simple lightning protection measures, such as grounding or lighting rods, are implemented to reduce the risk due to lightning strikes. Howev...
