Protection systems play a key role for the safe and reliable operation of today’s electricity power systems. Properly working protection devices help to maintain the safety of the system and to safeguard assets from damage. SXJB-6600 Relay Protection Tester is the essential test tool for relay protection technicians.

Features:

• To meet all the test requirements. 6 binary current and 6 binary voltage output simultaneously. Current 30A/binary, voltage 125V/binary.  6 binary current paralleled can reached to 180A. It’s not only can test on traditional relays and protection devices, but also can test on various microcomputer protection, especially better test for transformer differential protection and automatic bus transfer device.
• Can run independently, high performance IPC, CPU 300--600MHz, RAM 128M, HDD 6-12G, Window XP system. It also can be outside connected with computer.
• Stainless steel panel and keyboard, touch type mouse.
• High performance D/A converter.  High fidelity linear power amplifier, to ensure small current’s precision, and large current’s stability.
• USB port, to connect with PC directly.
• AC voltage & current, DC voltage & current, variable amplitude, binary angle, frequency could be output directly.  
• Switching input port could auto adapt passive (idle contact) active, and adapt activeinput polarity automatically. Regular working within ±250V input.
• Various protective fixed value could be scanned and tested, and store the test data by real time. Vector graphic and print report.
