4 FAQs about High voltage switchgear cannot automatically store energy

Is high voltage switchgear a greener and smarter transmission system?

This contribution highlights some important research and technology trends in high voltage (HV) switchgear development for reaching greener and smarter electricity transmission systems. In AC transmission, the focus is on the replacement of SF 6, which is a strong greenhouse gas, in HV switchgear.

What is high voltage switchgear?

High voltage (HV) switchgear is crucial for the transmission and control of electric power in power grids [1 - 3]. It includes HV AC circuit-breakers (CB) of live tank type (LTB), dead-tank type (DTB) and gas-insulated switchgear (GIS); see Fig. 1. Requirements are defined in international standards, e.g., [4, 5].

What is high-voltage HVDC transmission?

With the need to electrify the global energy system, high-voltage HVDC transmission will play an important role for transmission of electric power from remote renewable energy sources, such as offshore wind installations. Today this is done by radial HVDC network structures for both wind power and hydropower.

Does HV switchgear use SF 6?

Present HV switchgear dominantly uses SF 6 as gas for insulation and interruption, e.g., . Since SF 6 is a strong greenhouse gas [7 - 10] with a global warming potential of 24 300 on the 100 year scale (GWP100), the search for alternatives has intensified since the 1990s.
