Measurement on the Geomagnetic Induced Current (GIC) at low latitude region in Malaysia

Journal of Physics: Conference Series, 2021
Abstract This paper study the existent of geomagnetic induced current (GIC) in Malaysia. The location for GIC measurement is conducted at Tenaga Nasional Berhad (TNB) substation 33KV transformer in Malaysia. The measurement is taken at the neutral cable of the 33KV transformer which is grounded to the earth. In order to verify the result

Space Weather Impact on the Scandinavian Interconnected Power Transmission System [PDF]

, 2015
Geomagnetic storms (GMS) can seriously affect high voltage transmission power grids. More specifically, GMS can inject geomagnetically induced currents (GICs) into the power network, thus causing instabilities and eventually leading to grid collapse ...
