Power frequency line parameter tester

KDXL-IIPower frequency line parameter testerA high-precision instrument specifically designed for measuring power frequency parameters of transmission lines, capable of precise measurement of a series of power frequency parameters of transmission lines. This instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation and learning. It can replace the previous method of measuring line parameters using multiple meters, with simple wiring, easy testing and recording, greatly improving work efficiency. It uses a large 7-inch true color LCD screen as the display window, with graphical menu operation and Chinese character prompts. It integrates multiple parameters into one screen display interface, and has a friendly human-machine dialogue interface,

1. It can measure various related parameters such as positive and zero sequence, phase to phase, line to ground, effective voltage, effective current, active power, reactive power, etc. of transmission lines.

2. Allow external voltage transformers and current transformers for extended range measurement.

3. Voltage circuit width limit: The maximum voltage that can be measured is 750V, and accuracy can be ensured without switching gears. The instrument itself will not be damaged due to incorrect voltage gear selection.

4. Large screen, high brightness true color LCD display, full Chinese character menu and operation prompts for friendly human-machine dialogue, silicone buttons for easier operation, LCD with brightness adjustment, suitable for winter and summer seasons.

5. The instrument is equipped with a miniature high-speed thermal printer, and users can print the test data at any time through the miniature printer.

6. For users equipped with high-voltage measuring vehicles, an RS232 serial port is reserved for communication with computers, which can expand the function of uploading verification data and achieve centralized data management.
