High voltage switchgear is any switchgear used to connect or disconnect a part of a high-voltage power system. These switchgear are essential elements for the protection and safe operation, without interruption, of a high voltage power system. This type of equipment is important because it is directly linked to the quality of the electricity supply.

The International Electrotechnical Commission defines "high voltage" as a voltage above 1,000 Volts for alternating current and above 1500 V for direct current.
