Product introduction

NAYXL series transmission Line Power / Line Pilot tester is designed to test transformer loss parameter, the power frequency parameters and pilot frequency parameters of transmission line (such as overhead line, cables and overhead lines combined with cable).The power frequency parameters includes positive sequence capacitance, positive sequence impedance, zero sequence capacitance, zero sequence impedance, mutual inductance and coupling, capacitance and so on.

Also called name

Transmission line power frequency parameters testing system; Transmission line pilot frequency parameters tester; Transmission line test set; Power line tester.

NAYXL Transmission Line Pilot Frequency Parameters Tester

Product characteristics

1. Fast and accurately measuring the positive sequence capacitance, zero sequence capacitance, positive sequence impedance, zero sequence impedance and other parameters of transmission lines, it also can measure the mutual inductive reactance and coupling capacitance between the lines.

2 Strong anti-interference ability, can accurately measure under the condition of the ratio between power frequency signal and pilot frequency signal is 1:10.

3. External wiring is simple, only one time to access the lead of the line to complete all the line parameters measurements. Completely solve the problems of the existing test methods which cause cumbersome wiring switching procedure and the interference of stability and accuracy.

4. The instrument with high speed single chip microcomputer as the core, to achieve the integration of test power, meter and calculation model, make a truck of equipment concentrated into a single instrument.

5. The instrument uses 320*240 large screen dot matrix LCD, operated with the rotating mouse imported from United States, embedded mini-printer to print the results, the operation is very simple.

6. Instrument testing process is fast, automatically complete test mode control, boost-buck control, data measurement and calculation, and print measurement results, one minute to complete a parameter measurement, the test time is shortened, the workload is greatly reduced.

7. High accuracy measurement, the instrument itself provides three groups of pilot frequency power supply (45Hz/57.5Hz 45Hz/55Hz 47.5Hz/55Hz) which is close to power frequency, it can easily separate frequency and clutter, effectively achieve high-precision measurement of small signals.
