Wed, Feb 12, 2020 12:00 PM - 1:00 PM CET
The webinar will be based on the content of TB 780 which collected and evaluated digitally measured magnetic field environments throughout the world, with emphasis on the larger geomagnetic storms that have occurred since 1989. This data collection effort emphasized 3 basic types of geomagnetic storm waveforms of direct interest to the electric power industry: Sudden Impulse (SI) waveforms, Electrojet waveforms, and Coronal Hole High Speed Stream (CHHSS) waveforms. Each of these types of waveforms induces different geomagnetically induced currents (GICs) that have different magnitudes, time durations and variations with latitude on the Earth.
This webinar is presented by Dr William A. RADASKY, convener of CIGRE Working Group C4.32, "Understanding of the geomagnetic storm environment for high voltage power grid", that published Technical Brochure 780 (available from www.e-cigre.org), in 2019.
The registration to this webinar is free for all, CIGRE members and non-members.
