What is the difference between surge arrestor and bushing?
The difference between a surge arrestor and a bushing is significant in electrical systems. Understanding these components can help you ensure safety and efficiency. Let’s explore their functions and distinctions. Understanding Surge Arrestors Surge arrestors are devices designed to protect electrical equipment from voltage spikes. They act as a shield against surges caused by lightning or switching operations. When a surge occurs, the arrestor diverts excess voltage away from sensitive equipment. This prevents damage and prolongs the lifespan of electrical systems. Surge arrestors come in various types, including metal oxide varistors (MOVs) and gas discharge tubes (GDTs). Each type has specific voltage ratings and response times. Selecting the right surge arrestor is crucial for effective protection. Exploring Bushings Bushings, on the other hand, are insulating devices used in electrical equipment. They provide a safe passage for electrical conductors through barriers, lik...
