Kumwell has researched and developed "Network Lightning Warning Systems" to be accurate as Federal Aviation Administration (FAA) recommendation and effective according to IEC 62793: 2016.
IEC 62793: 2016 establishes four phases in the evolution of a thunderstorm;
1 - Initial Phase. Electromagnetic field rises.
2 - Growth Phase. Intra-cloud and cloud-to-cloud lightning.
3 - Mature Phase. Cloud-to-cloud and cloud-to-ground lightning.
4 - Dissipation Phase. Number of lightning bolts decreases.
According to these four phases of a thunderstorm, the standard classifies the following detectors;
Class A detectors - Detect thunderstorm during its whole life cycle (phases 1 to 4).
Class B detectors - Detect cloud-to-cloud and cloud-to-ground lightning (phases 2 to 4).
Class C detectors - Detect only cloud-to-ground lightning (phases 3 to 4).
Class D detectors - Detect cloud-to-ground lightning (phases 3) but with limited performance.
The processing between high accuracy lightning data where obtained from Kumwell Lightning Detection Network and high accuracy electric field data where obtained from Kumwell E-Field Network, resulting in a high accuracy early warning of the system. Thus the lightning warning system can be alert in Real-Time with high efficient and high accuracy notification.
All infomation from sensors sent to Kumwell computer main server and made computational model according presetting condition to acheive best warning.
Customer can access data sites of warning and graphical interface with computer user via web browser.
Customize local interface with additional warning lamps and sound services.
Kumwell Network Lightning Warning System Configuration Devices
Optional
Alarm Viewer Software
 |
Kumwell has developed software that adds unlimited lightning warning customization. Also, it can detect lightning data with a lightning current (value of 4 kA or more), data from the clouds to clouds (CC) or clouds to ground (CG) more than 95% efficiency at high accuracy, and has Fail to Alarm Ratio (FAR) less than 5% it can be displayed through the notification report. Alarm Viewer Software can alert lightning by displaying data, such as lightning alarm level, historical strokes, lightning points (time, magnitude of lightning strength, latitude-longitude), active zones, weather, and electrostatic fields (graph). It can also be customized and alerted via the LINE application when there is a lightning event around personal customer. |
 |
The program will alert the user if it is possible to have a lightning strike around the users. The notification is divided into 4 statuses, which are · Level 3 - Red light means the highest chance of a lightning strike. · Level 2 - Orange light means very high chance of a lightning strike. · Level 1 - Blue light means a primary warning. · Clear Level - Green light means a normal situation. |
System Architecture
Technical Data
Application
The KNLWS is suitable for use in all open areas where human traffic and / or sensitive operations are subjected to the threat of lightning strikes. In situations where large open areas covering many kilometres require monitoring, KNLWS provides a high degree of accuracy in providing a safe working environment.
Typical industry and recreational applications for the KNLWS include:
|
• Military |
• Construction sites |
|
• Airports |
• Ship loading facilities |
|
• Refuelling facilities |
• Power generation |
|
• Oil and Gas facilities |
• School |
|
• Theme parks |
• Horse racing tracks |
|
• Golf courses |
• Sports stadiums |
|
• Rail and Transport |
• Industrial |
|
• Open air events such as festivals and concerts |
• Mining sites including applications where |
|
• General outdoor recreational activities |
explosives are used for blasting purposes |
