Fault Location of Lightning Strikes Using Residual Analysis Based on an Adaptive Kalman Filter
Lightning strikes are the significant cause of transient, faults, and outages in electric power transmission and distribution systems. The double-exponential function is proposed to simulate the decaying part of the measured lightning current.

An Improved TDOA Lightning Location Approach Considering L-M Algorithm and Acoustics
In the conventional lightning location system (LLS) based on time difference of arrival (TDOA), the nonlinear equations in lightning location calculation easily get to be divergent when the time information acquired from electromagnetic sensors is ...

Lightning Sferics for Lightning Location – Complex Analysis
<p>Lightning location networks commonly use the time stamps of the received radio waveforms from lightning flashes (sferics) at numerous stations to determine a single lightning flash location. In order to extract more information from the recorded lightning waveforms, a complex analysis of the received electromagnetic waves is ...

VHF Direction Finder for Lightning Location [PDF]
Abstract A VHF direction finder based on the technique originally proposed by Oetzel and Pierce for the detection of sferics from lightning has been field tested. Cianos et al. reported a successful test of the same technique using sferics at 30 MHz. In our measurements, sferics in the frequency range 82–88 MHz are received by two antennas separated by
