Product Introduction

       NDXL-G Transmission Line Power Frequency Parameter Tester is a high-precision instrument developed and produced by our company specifically for power frequency parameter measurement of transmission lines. It can accurately measure a series of power frequency parameters for transmission lines of various voltage levels.

       This instrument features small size, light weight, high measurement accuracy, excellent stability, and easy operation. It can replace the traditional multi-meter method for measuring line parameters, with simple wiring and convenient testing and recording, greatly improving work efficiency.
       It uses a large-screen graphical LCD as the display window, with graphical menu operations and Chinese character prompts. The display interface integrates multiple parameters on one screen, providing a user-friendly interface that is simple and fast to use, making it the preferred product for users at all levels.

Product Features

☆、Can measure various related parameters of transmission lines, such as positive sequence and zero sequence, phase-to-phase, line-to-ground, voltage RMS, current RMS, active power, reactive power, etc.
☆、Allows external connection of voltage transformers and current transformers for extended range measurement.
☆、Wide voltage circuit range: Voltage can be measured up to 750V without switching ranges, ensuring accuracy. It will not damage the instrument due to incorrect voltage range selection.
☆、Large-screen, high-brightness LCD display with full Chinese menu and operation prompts for user-friendly interaction. Touch keys make operation easier, and the LCD brightness is adjustable to adapt to different seasons.
☆、The instrument is equipped with a miniature high-speed thermal printer, allowing users to print test data at any time.
☆、For users with high-voltage measurement vehicles, an RS232 serial port for computer communication is reserved, which can be expanded for calibration data upload and centralized data management.
