What is another word for spike arrester?
Pronunciation: [spˈa͡ɪk ɐɹˈɛstə] (IPA) 
A "spike arrester" is a device designed to protect electrical equipment from voltage spikes. Synonyms for this term include surge suppressor, surge protector, lightning arrester, high voltage protector, and transient voltage suppressor. Surge suppressors or protectors are perhaps the most commonly used synonym for spike arresters. They are often used to protect sensitive electrical equipment such as computers, TVs, and other electronic devices from power surges. Lightening arresters are typically used in outdoor electrical installations to protect equipment from lightning strikes, while transient voltage suppressors are used to protect against short-duration, high-energy voltage spikes. High voltage protectors, on the other hand, are designed to safeguard equipment against high levels of voltage.
