General Information:
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-3400 Relay Protection Tester is the essential test tool for relay protection technicians.
Features:
- Windows XP system, Great human interface.
- Rotary mouse to operate easily.
- USB port can be used per unit or connected with a laptop.
- High performance D/A converter. High precision waveform and excellent linearity.
- AC voltage & current, DC voltage & current, variable amplitude, phase angle, frequency could be output directly.
- Switching input port could auto adapt passive (idle contact) active, and adapt active input 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.
