Summary
This paper presents the first operational results of a real-time lightning current measurement system installed on a transmission line tower equipped with line surge arresters (LSAs) in the
Read more Read lessCroatian transmission network. The system enables accurate monitoring of lightning currents and operational transients, providing critical data for flashover rate estimation, EMT model validation, surge arrester assessment, and fault analysis. Laboratory tests confirmed waveform accuracy, and successful remote communication demonstrates reliable field operation. Field measurements recorded three lightning-related events and one switching-related event, validating the system’s ability to distinguish between different transient types. The paper also illustrates the application of signal processing and filtering techniques. Strategic placement of monitoring systems allows efficient data collection and supports the development of smarter and more resilient transmission networks.
