　　Line parameter testerIt is a high-precision instrument developed and researched by our company specifically for measuring power frequency parameters of transmission lines. It can accurately measure a series of power frequency parameters of transmission lines.

　　Line parameter testerIt 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, convenient testing and recording, greatly improving work efficiency. It uses a large screen image LCD as the display window, with graphical menu operations and Chinese character prompts. It integrates multiple parameters into a single screen display interface, with a friendly human-machine dialogue interface, easy and fast to use, and is the * product for users at all levels.

Features

◆ 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

◆ Allow external voltage transformers and current transformers for extended range measurement

Voltage circuit width limit: The maximum voltage can be measured up to 750V without switching gears to ensure accuracy. Will not cause damage to the instrument itself due to incorrect voltage gear selection

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

Users can print out the test data at any time through an external micro printer connected to the 232 interface (the 232 interface is an optional feature)

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
