Relay protection tester

Function and use
It can verify all kinds of relays (such as current, 전압, inverse time, power direction, impedance, differential, low cycle, synchronous, 빈도, DC, intermediate, 시간, 등.) and microcomputer protection, and can simulate all kinds of complex transient, permanent, transformational faults for whole group tests.

기술적 특성
Voltage and current output Flexible combined output up to 6 phase voltage and 6 phase current, can be combined to achieve conventional 4 phase voltage, 3 phase current type, 6 phase voltage type, 6 phase current type, 그리고 12 phase output mode, can be compatible with traditional various test methods.

The device panel is equipped with trackball mouse, optimized keyboard and large-screen TFT LCD display, and built-in Chinese Windows platform operating software. Boot can be used, 작동하기 쉬운.
Dual operation mode In addition to stand-alone operation, the device can also be connected to an external laptop or desktop computer for operation, the two ways of function is consistent, truly complete dual operation mode.

The output end of the new high-fidelity linear power amplifier has always insisted on using high-fidelity and high-reliability modular linear power amplifier, rather than switching power amplifier. It will not cause high and medium frequency interference to the test site, and ensure the smooth and accurate waveform from large current to small current.

The output part of the high-performance host adopts DSP control, which has fast operation speed, strong real-time digital signal processing ability, wide transmission frequency band and high resolution D/A conversion control. The output waveform precision is high, the distortion is small and the linearity is good. A lot of technology and precision components and materials are used, and professional structural design is carried out, so the device is small in size, light in weight, full in function, 휴대하기 쉬운, can be started to work, and flow test is very convenient.

It can complete a variety of large-scale and complex calibration work with high degree of automation, and can easily test and scan various protection values, perform fault playback, store test data in real time, display vector images, and print reports online. The 6-phase current facilitates three-phase differential protection testing.

Independent dedicated DC power output with one 110V and 220V dedicated adjustable DC power output.

Contact rich with 10 contact inputs and 4 empty contact outputs. The input contact is compatible with null contact and 0-250V potential contact, which can be automatically identified intelligently.

Perfect self-protection function Heat dissipation structure design is reasonable, hardware protection measures are reliable and perfect, with power soft start function, software for fault self-diagnosis and output lock and other functions.
