Chapter One Device Features and Technical Parameters
Section One Main Features
Standard 4-phase voltage and 3-phase current output With 4-phase voltage and 3-phase current output, it is convenient to carry out various combination outputs for various types of protection tests. The single-phase voltage can output up to 120V, the single-phase current can output up to 40A （10 seconds）, the current three can output 120A, the fourth phase voltage Ux is a multi-function voltage item, which can be set to 4 types of 3U0 or check the same voltage, or Output at any voltage value.
The single machine is easy to operate. The single machine is operated by a convenient and flexible rotating mouse through the large-screen LCD display, all displayed in Chinese. It can complete most of the field test and verification work, can verify various relays and microcomputer protections, and can simulate various complex transient, permanent, and conversion faults for a whole set of tests. It can be used after booting, and the operation is convenient and quick.
Dual operation mode, connected to the computer and running through a full set of Chinese operating software on the Windows platform, can perform various large-scale, complex and more automated calibration tasks, can easily test and scan various protection settings, and can store and test in real time Data, display vector diagrams, draw fault waveforms, print reports online, etc.
The software has powerful functions and can complete various large-scale and complex calibration tasks with a high degree of automation, such as three-phase differential test, factory power quick-cutting, automatic switch-on test, line protection inspection and simultaneous reclosing, etc. It can easily test and scan various Protect the fixed value, perform fault playback, store test data in real time, display vector diagrams, and print reports online.
Rich switch contacts Three-phase 7-way contact input and 2 pairs of empty contact output. The input contacts are empty contacts and compatible with 0～250V potential contacts, which can be intelligently and automatically identified. The input and output contacts can be expanded according to user needs.
Large-screen LCD display This machine adopts a 320×240 dot matrix large-screen high-resolution graphic LCD display. All operation processes are set on the display. The operation interface and test results are displayed in Chinese, and the display is intuitive and clear.
Self-protection It adopts a reasonably designed heat dissipation structure, and has a variety of reliable and complete protection measures, soft start of the power supply, and certain fault self-diagnosis and blocking functions.
has an independent dedicated DC power output The device has a 110V and 220V dedicated DC power output.
High performance-price ratio It is a cross-professional joint design product that integrates advanced scientific and technological achievements from multiple disciplines. It combines the performance of a large-scale tester and the price of a small-scale tester, and has a high performance-price ratio.
