Arresters, also known as surge arresters, are devices designed to protect electrical systems from voltage surges and transient overvoltages. While arresters are an essential component in electrical installations, there are several other synonyms for the term that are commonly used. These include overvoltage protectors, surge suppressors, surge protectors, voltage limiters, and lightning arresters. All of these terms describe devices used to prevent damage caused by power spikes or electrical surges, and they are especially important in locations that are prone to lightning strikes or other electrical faults. When selecting an arrester for a particular application, it is critical to consider factors such as voltage rating, installation location, and response time.
