KDXL-A transmission line parameter tester has the advantages of small size, light weight, high measurement accuracy, good stability, simple operation and easy to learn, which can replace the previous method of measuring line parameters using multi-table method, simple connection, convenient testing and recording, and greatly improve the work efficiency. It uses the large-screen LCD as the display window, the menu operation in the form of the picture is equipped with Chinese characters, and the display interface of multi-parameters is set in one screen. The human-machine dialogue interface is friendly, easy to use and fast.

1, can measure the transmission line positive sequence and zero sequence, phase to phase, line to ground and other related parameters, voltage effective value, current effective value, active power, reactive power and other parameters.
2, allow external voltage transformer and current transformer for extended range measurement.
3, the voltage circuit width limit: the maximum voltage can be measured to 750V, without switching gears to ensure accuracy. It will not damage the instrument itself due to the wrong voltage gear selection.
4, large screen, high brightness LCD display, Chinese menu and operation prompts to achieve friendly human-machine dialogue, touch the button to make the operation easier, LCD with brightness adjustment, can adapt to winter and summer seasons.
5, the instrument is equipped with a miniature high-speed thermal printer, the user can print out the test data through the micro printer in real time.
6. The RS232 serial port for communication with the computer is reserved for the users of the high-voltage measuring vehicle, which can expand the uploading function of calibration data and realize the centralized management of data.
