What Is Switchgear?
Switchgear is an apparatus used for the controlled distribution of electrical power, particularly at high or extra-high voltages. It typically houses components like switching devices, protective relays, and meters within a metal enclosure.
There are two main types of switchgear: enclosed and open. The enclosed type is designed with safety as the priority, whereas the open type is valued for its ease of maintenance.
Switchgear plays a vital role in a wide range of applications such as power plants, substations, factories, and buildings. It is key to ensuring the safety and reliability of an electrical infrastructure. Its functions include the opening and closing of circuits, circuit interruption, and the measurement of voltage and current. These capabilities are crucial for maintaining the normal operation of the electrical system and safely disconnecting power in the event of any malfunctions.
