System performance

• Brand-new protection idea
• Arc comes with equipment fault. Arc is energy source for severe damage on equipment. Shorten the arc duration can avoid equipment damage essentially.

• Protection criterion
• Set action criterion according to field application. The criterion can be divided to arc light intensity criterion, arc light intensity and fault current criterion.

• High speed fault response
• SAQE-A200 optimizes response velocity on the basis of safety, just 5-7ms is needed to trip after detection.

• Accurate fault location
• Determine fault location accurately the time fault happens. Master unit and I/O unit are reflected by indicator light and logout, and fault information and location are uploaded to power monitoring system quickly.

• Modular construction satisfies low-end system of various scheme
• SAQE-A200 master unit applies PC modular construction, on the basis standard configuration, offer I/O board, communication board, arc board and fiber board, offering flexible solution scheme and satisfying user requirements.

• Cost-effective system solution scheme
• Master unit and ex unit can form comprehensive arc protection system, and can work uniquely, forming economical arc protection system.

• Flexible dilatation and promotion enhance adaptability to field.
• Distributed structure of SAQE-A200 arc protection system can add master unit board, I/O unit and sensor at any time, and set protection logic flexibly to satisfy field requirement.

• Equal system configuration, redundant design
• Master units of arc protection system with more than two bus are equal in whole communication system. And the mater units can back up each other, satisfying the redundancy requirement and enhancing system stability.

• 24-hour system self-test
• The main unit SAQE-A200 is able to patrol all equipment in the system. It ensures the normal state of the I/O units, the point sensors and the Fiber Optic Sensors. It also makes the correct connection with system. When any equipment hardware fault or connected abnormally, it can send out alarm signal through ERROR Indicator and LCD event information. Then upload them to Background monitoring system making detailed fault information that can be analyzed.

• Detailed fault information, convenient for fault analysis
• Master units of SAQE-A200 can record incidences, faults and waves. It can be viewed by VIEWAY on mater unit and by MARCS software, offering original data for fault analysis.
