Relay protection tester

Function and use
It can verify all kinds of relays (such as current, волтаж, inverse time, power direction, impedance, differential, low cycle, synchronous, честота, DC, intermediate, време, и т.н.) and microcomputer protection, and can simulate all kinds of complex transient and transformational faults for whole group tests.

Relay protection tester

техническа характеристика
 Intelligent host The host adopts high-speed and high-performance digital signal processor with fast operation speed and wide transmission frequency band. The software uses double precision algorithm to produce high-precision waveform of each phase. Due to the integrated structure, each part is closely combined, the data transmission distance is short, and the structure is compact.
 Single machine independent operation device is operated by convenient and flexible rotating mouse through large LCD screen, Chinese display. It can complete most of the on-site test verification work, and can verify all kinds of relays (such as current, волтаж, inverse time, power direction, impedance, differential, low cycle, synchronous, честота, DC, intermediate, време, и т.н.) and microcomputer protection, and can simulate all kinds of complex transient and transformational faults for whole group tests.
 can complete a variety of large and complex calibration work with high degree of automation, such as differential test, standby automatic test, line protection inspection and reclosing at the same time, и т.н., can easily test and scan a variety of protection fixed values, real-time storage of test data, display vector images, и т.н.
 large-screen LCD display The machine adopts large-screen high-resolution graphic LCD display, the operation process is set on the display, the operation interface and test results are displayed in Chinese, the display is intuitive and clear.
 “fool” operation adopts the new controller “rotating mouse”, with multiple shortcut keys to operate, greatly simplifying the structure of the operation part, лесен за работа, бърз, easy to master.
 The new high-fidelity power amplifier output stage adopts the new high-power modular high-fidelity power amplifier components, which can be used as both current output and voltage output. The output power is large, the precision is good, and the reliability is high.
 Current, voltage direct output Phase voltage, phase current using DC power amplifier output mode, can directly output AC voltage, AC current, DC напрежение, DC current, and variable Angle, variable frequency, can be superimposed 1-20 harmonics.
 Self-protection Adopt reasonable design of heat dissipation structure, and has a variety of reliable and perfect protection measures and power soft start, and a certain fault self-diagnosis and blocking function.
 with independent dedicated DC power output device with one 110V or 220V dedicated DC power output.
 Contact rich has 8 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.
 The integrated single machine uses 220V AC power. Малък размер, леко тегло, Лесно за носене, flow test is convenient.
 high cost performance belongs to the cross-professional joint design products, which integrates the scientific and technological achievements of many professions. Both the performance of a large tester, and the price of a small tester, with a high performance-to-price ratio.
