Product Overview & Application Scenarios

The Handheld Optical Digital Relay Protection Tester is a portable testing device specifically designed for the construction and maintenance of smart substations. With the comprehensive development of smart substations, traditional debugging and maintenance instruments can no longer meet the needs for fiber - optic digital signal acquisition and observation. This tester, based on the DL/T 860 standard and powered by a low - power SOC platform with a dual - core ARM+FPGA architecture, offers a wide range of functions. It is capable of performing various operations such as message monitoring, traffic statistics, message storage, MU simulation, relay protection testing, optical power measurement, B - code time signal comparison, polarity testing, and phase comparison in the process layer network of smart substations. It is applicable to the commissioning and maintenance phases of substation construction, as well as to the testing needs of research institutions and equipment manufacturers. This device is of great significance for ensuring the safe and reliable operation of power grids.

Key Features & Advantages

Portability and User - Friendliness: Equipped with a 7 - inch high - resolution touch display and a built - in high - capacity lithium battery, the device has a long battery life of no less than 6 hours and weighs only 2.5 kg. Its tablet - style operation makes it easy to carry and operate on - site.

Multi - function Integration: It supports a variety of functions, including intelligent test template editing, SCD file import, message anomaly testing, phase comparison, transformer polarity testing, time synchronization detection, and SCD file comparison. This meets a wide range of testing requirements.

Efficiency: The tester can directly import SCD files from 500kV and 750kV smart substations. Users can add test items at will and save them as reusable test project files, which significantly improves the efficiency of later routine inspections and defect elimination.

Advanced Technology: Based on the IEC61850 communication standard system, it supports various message output and encoding methods, such as FT3, extended FT3, and DL/T 282 message output. It also supports UART encoding at baud rates of 2M/4M/6M/8M/10M and Manchester encoding at 5M/10M/20M, demonstrating strong adaptability.

Data Visualization: It features a virtual terminal graphical display function, which makes data flow clear and easy to understand, facilitating quick user comprehension and operation.

Real - time and Reliability: The device is equipped with a real - time alarm function and supports time synchronization. It can output optical IRIG - B(DC) and optical PPS timing signals to ensure the real - time and reliability of the testing process.

Expandability and Compatibility: It provides a USB port for copying images and messages, facilitating data storage and transmission. It also supports serial connection monitoring, allowing data parsing and analysis without interrupting on - site data transmission.

Operating Conditions

Working Temperature: - 10℃ to 50℃.

Humidity: ≤95%, non - condensing.

Additional Information

Data Storage and Transmission: Supports importing SCD files via USB drive and copying images and messages through the USB port for convenient data storage and transmission.

Compatibility: Supports various message output and encoding methods, with strong adaptability to meet the needs of different smart substations.

Extended Functions: Supports network stress testing, which can simulate various abnormal messages or traffic to test the reliability of equipment, providing strong support for equipment performance evaluation.

Maintenance & FAQs

Q: What should I do if the device freezes during use?

A: First, check if the device's battery is sufficient. If not, charge it promptly. If the battery is sufficient, try restarting the device. If the problem persists, there may be an internal fault in the device. It is recommended to contact the after - sales service center for repair.

Q: Why does the display screen show a mosaic or go black?

A: A mosaic or black screen on the display may be caused by strong external electromagnetic interference or internal hardware failure. Place the device in an interference - free environment and restart it. If the problem remains, contact the after - sales service center for inspection and repair.

Q: How to solve unstable data transmission during message monitoring?

A: Check if the connections between the device and the equipment under test are secure and if the interfaces are correctly connected. If the connections are normal, try reconfiguring the communication parameters of the device. If the problem persists, the communication module of the device may be faulty. Contact the after - sales service center for inspection and repair.

Q: What should I do if the battery life of the device is significantly shortened?

A: The battery life of a lithium battery will gradually decrease with prolonged use, which is normal. It is recommended to charge the device regularly and avoid overcharging or over - discharging for extended periods. If the battery life is significantly shortened, consider replacing the battery. It is recommended to contact the after - sales service center to purchase an original battery for replacement.

Q: How to solve message parsing errors during use?

A: Check if the device's software version is the latest. If not, update the software promptly. If the software version is up - to - date, try re - importing the SCD file or reconfiguring the message parameters. If the problem persists, there may be a hardware fault in the device. Contact the after - sales service center for inspection and repair.
