Product Introduction

Line parameter tester is a high precision instrument specially developed by our company for measuring power frequency parameters of transmission lines. It can measure a series of power frequency parameters of transmission lines precisely. The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, easy operation and so on. It can completely replace the previous method of measuring line parameters by multi-meter method. It has simple wiring, convenient testing and recording, and greatly improves work efficiency. It uses large screen graphical liquid crystal as display window, graphical menu operation and Chinese character prompt, set multiple parameters in one screen display interface, friendly man-machine dialogue interface, easy and fast to use, is the preferred product for users at all levels.
Product parameters

Input characteristics

Voltage measurement range: 0 ~ 750V wide range, one gear can ensure accuracy.

Current measurement range: 0 ~ 100A, internal automatic switching range.

Accuracy

Voltage and current: +0.5%

Power: +0.5%(Cos>0.1), +1.0%(0.02)

Impedance, capacitance and inductance: 0.5%

Resistance, Capacitance, Inductance, Conductance, Admittance: 0.5%

Working Temperature: -10 ~40

Working power supply: AC 160V~400V

Insulation: The insulation resistance of the input voltage and current to the housing is greater than or equal to 100M.

Product features

1. It can measure all kinds of related parameters, such as positive sequence and zero sequence, phase to phase, line to ground, voltage effective value, current effective value, active power, reactive power and so on.

2. Extended range measurement of external voltage transformer and current transformer is allowed.

3. Width limit of voltage circuit: The maximum voltage can be measured to 750V, and the accuracy can be guaranteed without switching gears. The instrument itself will not be damaged due to the wrong selection of voltage shifts.

4. Large screen, high brightness LCD display, full Chinese menu and operation hints to achieve friendly man-machine dialogue, touch keys to make the operation easier, LCD band brightness adjustment, can adapt to winter and summer seasons.

5. Users can print the test data through 232 interface and external micro printer at any time (232 interface is optional function).

6. The RS232 serial port which communicates with the computer is reserved for the users who are equipped with the high-voltage measuring vehicle. It can expand the function of uploading calibration data and realize the centralized management of data.
