What is the difference between a surge protector and a lightning arrester? 【Video】@ Chemical Chat Daily AT16

Surge protectors and lightning arresters are two types of protection devices commonly used in electrical systems, and they have different functions and application scenarios: 1. **Surge Protector**: – It is primarily used to protect electrical equipment from damage caused by voltage surges, which can be resulting from lightning strikes, power grid failures, etc. - Surge protectors can instantly absorb or divert excessive voltage, protecting the electrical devices connected downstream. - It is commonly used in homes, offices, and any place where electronic devices need to be protected from voltage fluctuations. 2. **Lightning Arrester**: - Lightning arresters are designed to protect buildings, communication facilities, power systems, and other structures from damage caused by direct lightning strikes. - It provides a low-impedance path that allows lightning to be safely directed to the ground, thereby protecting buildings and equipment. - Lightning arresters are usually installed at high locations on buildings, such as on rooftops or other protruding parts. In general, surge protectors are used primarily to protect electrical equipment from voltage surges, while lightning arresters are used to protect an entire building or facility from direct lightning strikes. Although both are related to electrical protection, there are clear differences in their functions and application areas. .
