Answer: The primary functions of switchgear are to protect, control, and isolate an electrical system. It protects the system from overcurrents and short circuits by automatically interrupting the flow of electricity when a fault occurs. Switchgear also allows for the control of power flow, enabling operators to connect and disconnect circuits as needed. Finally, it provides a means to isolate sections of the system for safe inspection and maintenance. At Ningbo Changshi, we offer a wide array of tools and equipment essential for the safe handling and operation of switchgear components, from circuit breaker maintenance to protective relay testing.
