l Technical Features
l Standard 4 Phase Voltages & 3 Phase Currents Output with Accuracy 0.1%
Standard 4U3I output are available, which can be combined conveniently for all kinds of relay protection tests. Each phase voltage can reach 120V. 3I in parallel can reach 120A. The 4th phase voltage Ux is multi-functional voltage, which can be set to be 4 kinds of 3U0 , synchronization check voltage or arbitrary output voltage.
l Convenient Operation Flexible rotary mouse are used for convenient operation, which can be displayed intuitively on large-screen LCD in Chinese. Fit for most of tests, the tester can not only test all kinds of relays (such as current, voltage, normal inverse, power direction, impedance, differential, low-cycle, synchronization, frequency, direct current, auxiliary and time) and microcomputer protection units, but can also simulate temporary, permanent and conversion faults from single-phase to three-phase for group test. Operation is accessible right after switching on, which is convenient and speedy.
l Double Operation Modes (stand-alone or connected with PC) Through the complete Chinese operation software on Windows platform, tester is fit for various kinds of large-scale, complex and highly-automatic tests. All kinds of protection settings are tested and scanned conveniently. Functions such as fault waveform playback, test data storing, vector graph displaying and test report saving and printing, etc. are available.
l High Performance Linear Amplifier We insist on using high fidelity and high reliable modular linear amplifier for output units instead of the switch-model amplifier, which provides extremely high precision small-signal, delicate and smooth waveform. It would not generate HF or MF interference, so to guarantee the waveform of all the large and small current to be smooth and in high precision.
l High Performance Mainframe
l Abundant Contacts 10 input contacts and 8 pairs free output contacts are available in RTS 706. Input contacts are compatible for free contacts and 0~250V potential contacts, with adaptive identification. Input and output contacts can be expanded as required. Abundant contacts make it convenient for complex ATT test.
l Software with Powerful Function Tester isfit for various kinds of large-scale, complex and highly-automatic tests, such as three-phase differential test, auxiliary power quick switching, AAT, line protection synchronous reclose.
l AAT Test 10 digital inputs and 8 pairs digital outputs are available for AAT test. The device has beautiful interface which can intuitively display the connection diagrams of all kinds of systems, the condition of all switch contacts, current/voltage amplitude. The whole process of AAT is tested, recorded and displayed directly and conveniently.
l Special Test Software for Mainstream Manufacturers’ Protection Devices A series of special test software for protection devices of NARI RELAYS ELECTRIC CO,. LTS, XJ Group Corporation, SIFANG, Beijing Devote Power Systems Automatic CO,. LTD, etc. are developed, which can test relays completely and automatically.
l Perfect Self-Protection Suitable heat dissipation structure and diversified self-protection are available, such as power supply soft-start, faults auto-diagnosis and blockage functions.
l Independent Adjustable DC Power Supply One power supply (110V/220V DC) for exclusive use.
l New Integrated Structure Designed by several industries, tester synthesizes the advanced technologies of many professions. It’s small-sized, light-weight (only 14kg), and with high cost performance.
