The internal modular design of the instrument can independently complete the testing and debugging of devices and components in the professional fields of relay protection, excitation, metering, wave recording, etc.
High performance Industrial control computer is adopted as the controlling computer, through which you can run the windows operating system directly. 10.1"TFT true color LCD display, tracking ball and optimized keyboard are allocated on the faceplate of this tester, which can be used without the external mouse and keyboard. USB interface, 10-100M net mouth and serial communication interface are located on the back plate of this tester, through which you can access data, communicate data and upgrade software conveniently.
High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced. Since integrative structure is adopted,the structure of the tester is layed compactly.The distance of data transmission is short with tight structure, which overcome the problem of fewer points of waveform output due to long data communicational line and narrow frequency band when using the test controller controlled directly by PC.
