Questions & Step-by-Step Solutions
Which switchgear component is primarily used to interrupt fault currents?
Step 1: Understand what switchgear is. Switchgear is a collection of electrical devices used to control, protect, and isolate electrical equipment.
Step 2: Learn about fault currents. Fault currents are abnormal currents that occur during electrical faults, like short circuits.
Step 3: Identify the purpose of circuit breakers. Circuit breakers are designed to automatically interrupt the flow of electricity when a fault current is detected.
Step 4: Conclude that circuit breakers are the switchgear components that specifically interrupt fault currents to protect electrical systems.
