The International Symposium on Lightning Protection (SIPDA) is a scientific event organized every two years that has as main goals to contribute to the discussion and dissemination of innovations in lightning technology. The event covers all lightning-related aspects, including lightning physics and characterization, measurements, modeling techniques, detection and location systems, grounding, protection methods, and accidents and damages associated with the phenomenon.

The event is organized by the Institute of Energy and Environment of the University of São Paulo (IEE/USP) with the technical co-sponsorship of the Institute of Electrical and Electronics Engineers (IEEE) and support of the Federal University of Minas Gerais (UFMG) and the National Institute for Space Research (INPE).
