Intelligent substation optical digital tester

Intelligent substation optical digital testerProduct Introduction:

With the comprehensive construction of smart substations, a large number of digital intelligent electronic devices based on DL/T 860 standards, such as electronic transformers, merging units, intelligent terminals, and intelligent switches, have been applied in substations. The conventional instruments and meters used for debugging and maintenance are no longer able to meet the needs of signal acquisition and observation on site. In the new construction, debugging, and maintenance stages of intelligent substations, a dedicated instrument that is convenient to carry and operate is needed to observe the status of such fiber optic digital signals and detect the operating status of related intelligent equipment through output testing signals. The development and application of handheld optical digital testers have important practical significance for the construction of intelligent substations and the safe operation of power grids.

Intelligent substation optical digital testerIt is a handheld instrument designed according to relevant technical specifications such as DL/T 624-2010 Technical Conditions for Relay Protection Microcomputer Test Equipment, and based on the IEC61850 communication standard system, using a low-power SOC platform with dual core ARM+FPGA.

The substation optical digital tester adopts a flat panel operation mode, which has the functions of message monitoring, flow statistics, message storage, analog MU transmission, simple relay protection testing, optical power measurement, B-code time signal comparison, polarity testing and nuclear equality for the process layer network of intelligent substations. It can realize the function and performance testing of merging units, relay protection devices, measurement and control devices, and intelligent terminals, and is suitable for substations, various scientific research units, and equipment manufacturing enterprises.

Performance characteristics:

Developed on a highly integrated SOC hardware platform, using a secure, reliable, and stable embedded Linux system;

>7-inch 1280 * 800 high-resolution, capacitive full touch screen operation;

>Used for digital signal testing and analysis of intelligent stations, as well as relay protection debugging;

>Support intelligent testing template editing, allowing for the arbitrary addition of testing items during the testing process and saving them as reusable testing engineering files, improving testing efficiency during the later stages of calibration and defect elimination.
