Sectionalized single busbar configuration

• The application of SAQE series arc protection system in sectionalized single line busbar configuration system is shown in figure 1. Point sensor is utilized to monitor the arc in section I while fiber sensor in section II. When the arc signal is detected and the incoming current exceeds the set value, SAQE-A200 cut off the power supply selectively to prevent the equipment from damage caused by fault.
• When the arc fault of cable joint chamber is detected by sensor, SAQE-A12 could tirp the breaker directly so it does not affect the incoming line.
