What is BS EN IEC 62793 about?
BS EN IEC 62793 discusses thunderstorm warning systems for protection against lightning.
BS EN IEC 62793 specifies characteristics of thunderstorm warning systems (TWS). BS EN IEC 62793 focuses on implementing lightning hazard preventive measures. Single sensors or a network of sensors like a lightning location system can be used as TWS.
BS EN IEC 62793 specifies requirements for sensors and networks that collect accurate data of the relevant parameters thus, providing real-time information on lightning and atmospheric electric activity. It describes the application of the data collected in the form of warnings and historical data.
BS EN IEC 62793 defines guidelines for alarming methods, available techniques for TWSs, and informative examples of possible preventive actions.
Note 1: Under BS EN IEC 62793 lightning protection systems, portable systems are not covered.
Note 2: Thunderstorm-related phenomena such as rain, hail, wind, and satellite and radar-based thunderstorm detection techniques lies outside the scope of BS EN IEC 62793.
Who is BS EN IEC 62793 for?
BS EN IEC 62793 on thunderstorm warning systems is relevant to:
- Manufacturers of TWS
- Suppliers of TWS
- Developers of TWS
Why should you use BS EN IEC 62793?
Natural atmospheric electric activity and in particular cloud-to-ground lightning poses a serious threat to living beings and properties resulting in severe injuries and deaths every year. So, lightning can be a cause of the fire and may interrupt all kinds of industrial, cultural, political activities.
Development in technical systems used for real-time monitoring of natural atmospheric electric activity and lightning has increased. Systems of high-quality are thus, developed which provides valuable information when coordinated with a detailed plan of action.
Although many natural phenomena are subjected to statistical uncertainties due to which it is not possible to achieve precise information like when and where individual lightning will strike.
So, effectiveness on a large scale depends on the extent of risk involved along with planned decisions.
Requirements under BS EN IEC 62793 assist in collecting historical data and provide warnings regarding lightning activity.
BS EN IEC 62793 provides alarming methods and preventive actions to protect against lightning strikes in case of need.
BS EN IEC 62793 guides in building efficient TWS for warning against thunderstorms and lightning by providing available techniques for TWS.
BS EN IEC 62793 assists the user in adapting anticipated temporary preventive measures regarding the lightning activity.
What’s changed since the last update?
BS EN IEC 62793:2020 supersedes BS EN IEC 62793:2018 which is withdrawn. The main changes with respect to the previous edition are:
- Deletion in clause 5 regarding classes of TWS
- Portable devices are no longer covered
