Description

Micro-computer relay protection test device (all below we called relay tester) is a very important test tool to ensure electrical system under safe and realible work. It is inevitable trend to design new and high performance relay protection device with the high speed developing computer technology, microelectronic technology and power electronic technology.
 ZJB***0 micro-computer relay protection test device is our new designed product based on original technical requirements and field experience, and adopts new digital technology, high quality parts, mirco-computer system. The tester can independently finish the mirco-computer protection, relay protection, excitation, measure, fault recorder and so on. It is widely applied over electric, petrochemical project, metallurgy, railway, aviation, military for the scientific research, electric test and production.

Features:

• *-phase voltage and current output, realize *-phase voltage & *-phase current mode, *-phase voltage/current mode and **-phase output mode.
• High performance Industrial control computer is adopted as the controlling computer, 6.4"TFT true color LCD display.
• Output terminal uses high fedelity, high realible line amplifier, but not switch type, excellent performance. Do not impact high and middle frequency, ensure linearity from big current to small.
• Output part adopts DSP control, high-speed operation, real-time digital signal process, width transmit band, high pixel D/C conversion. High precise output wave, good linearity and small distortion. Professional design, small size, light weight, full functions, easily handcarry.
• Independent **0V & **0V dedicated and adjustable DC power output, easily for onsite test.
• New generation ***0 tester has **-road switch input and *-road switch output, easily do  automatic bus transfer test. Input contact is compatible with space contact and 0～**0V potential, and intelligently auto indentify.
• Prodive all kinds of auto test software modules and GPS sync trigger test ( selectable ).
• Can do all kinds of complicated calibration work, easily test and scan protection setting, and do fault recovery. real-time store test data, sector graphic showing, printing report.
• Excellent thermal design and structure, perfect hardware protection, power software startup, software self-diagnosis and interlock function.
