Electrical circuits are engineered to handle specific amounts of electricity. However, when an excessive current flows through, it can lead to overheating of the wires, potentially causing damage to essential electrical components or even fires. Switchgear plays a crucial role in protecting equipment connected to a power supply from the hazards of electrical overload.
Defining Switchgear
So, what exactly is switchgear? Switchgear is a broad term encompassing various switching devices designed to control, protect, and isolate power systems. This includes devices for regulating and measuring a power system, such as circuit breakers and similar technologies.
The Role of Switchgear
In the event of an electrical surge, efficient switchgear will activate, automatically halting the power flow and safeguarding the electrical systems from damage. Switchgear is also indispensable for de-energizing equipment, facilitating safe testing, maintenance, and fault correction.
Examples of Switchgear
Switchgear comprises a diverse range of systems and components, including switches, fuses, isolators, relays, circuit breakers, and lightning arresters.
Types of Switchgear
Switchgear systems are classified into three main types: low-voltage, medium-voltage, and high-voltage.
High-Voltage Switchgear
High-voltage switchgear is utilized to control power at levels of 75KV or higher. These systems are specifically designed for high-voltage applications and often incorporate advanced safety features to ensure reliability and protection.
