  • Profile: 1. Manual and automatic tests of voltage, current, frequency, power, impedance, harmonic, differential and synchronization relays; simulating various fault types for fixed value calibration of distance and zero sequence protection devices, full group tests of protection devices; GPS triggering function. The software presents all Chinese Windows interface, compatible with Windows XP. 2. Reliability ensured by its unique heat dissipation parts, with four high power exhaust fans in the instrument and installed temperature protector and measurer; these ensures excellent stability and reliability during heavy current and long time working. The current source itself already possesses the functions of open circuit protection and open circuit alarming, the voltage source has short circuit protection function, and chopped distortion detection as well as miss-wiring determining and alarming self-locking functions. It can perform dynamic monitoring of output waveform and display it. 3. Has isolated input contacts, compatible of idle contacts and electric potential contacts, which make various wiring connection ways possible. 4. Has five-channel voltage output, of which one channel is for auxiliary DC voltage, making it more convenient for field debugging. 5. Can run independent of a computer; it can independently output three-phase voltage and three-phase current, with arbitrary and continuously adjustable amplitudes and phase positions. Easy to operate, 320x240 large LCD display, all Chinese interface. When it’s running independently, it can measure the operating value and actuation time of various AC/DC relays, can make full group test, and can perform auto test. 6. Architectural inner frame structure, with anti-vibration and shock resistant high strength alloy machine box that makes the device able to stand vigorous vibration test. 7. Uses latest DSP and large scale programmable FPGA of American TI Company, with 1448-point waveform simulation, gearing the instrument with better transient response and frequency-amplitude characteristic. It's the first to have used 20bit serial port DA in China, which will further improve output precision. 1. Source voltage: single-phase AC 220V+10%, power 1,000VA; source frequency: 50HZ±10%. 2.
