A new localised lightning locating system — software implementation

Lightning mapping or locating systems are mainly based on either the time of arrival or the directional finder methods. For a localised region, it is desired that the coordinate of lightning strike within the region can be accurately determined. This works concerns the software implementation of the installed localised lightning locating system (LLLS) using LabView. The coordinate of lightning strike is calculated based on the measurement of lightning induced voltages and their arrival times at both ends of an overhead telephone line. Due to the small area involved, the accuracy of the coordinate calculation was shown to be much better than that obtained from the commercial country-wide lightning locating system.
