A signal lightning arrester is a device used to prevent lightning damage to signal lines.
It works by installing a circuit with a high resistance at the entrance to the signal line. This circuit counteracts the high voltage introduced into the signal line by lightning and also counteracts electromagnetic interference to ensure the normal operation of the signal line.
When lightning is introduced into the signal line, the signal lightning protector can quickly remove the high voltage through the high resistance path to avoid damage to the signal line and ensure the normal operation of the signal line.
