The ST arc protection device is a device used in power systems to quickly detect and protect arc faults based on the principle of dual judgment of current and arc light. It determines whether an arc fault has occurred by real-time monitoring of the current and light changes inside the switch cabinet. When an abnormal arc light is detected and the current exceeds the set threshold, the protection device will quickly issue a trip command to cut off the fault power supply, thereby preventing the fault from expanding and protecting the safety of equipment and personnel.
