Product Introduction
XLY-Y Transmission Line impedance tester
The Integrated different frequency test power, measuring instruments, and the mathematical model in one, eliminating strong interference effects and ensuring the safety of equipment, is extremely easy, quick, and accurate in measuring the frequency parameters of the power transmission line. The instrument is an integrated structure, built-in frequency conversion power module and variable frequency voltage control output power supply. The frequency can be changed to 45Hz and 55Hz, and the digital filtering technology is adopted to avoid the interference of the power frequency electric field on the test, and the problem of accurate measurement under the strong electric field interference is fundamentally solved. At the same time, it is suitable for the test of the generator power supply after all power failures.

Product Feature And Application
1. Fast and accurate measure of the positive sequence capacitance, positive sequence impedance, zero sequence capacitance, and zero sequence impedance. Can also measure the mutual inductance and coupling capacitors between the lines (line DC resistance used dedicated YTLRT to test)
2. Strong anti-interference ability, and accurate measurement under the condition of different frequencies and frequency interference signals in the ratio of 1:10.
3. External wiring is simple; only one access to the lead line of the tested line can complete all the line parameters measurement.
4. The Instrument takes a DSP digital signal processor as the core, integrating the test power, meter, and calculation model into one instrument. Big screen, rotation mouse operation mode, micro printer printing results, the operation is very convenient.
5. The test process is quick, automatically tests mode control, voltage step-up & step-down control, and data measurement, calculation, and prints the measuring results, a sequence parameter measurement completes in one and a half minutes; the test time is reduced, which can greatly reduce the workload, 5 minutes can complete the work that the traditional method used two hours.
6. High precision measurement, the instrument itself provides a different frequency AC power supply (52.5Hz, 47.5Hz), which is close to the power frequency, easy separation of power and other interference, and effectively realizes high precision measurement of small signals.
7. Can save 2048 sets of test data, and do data management and report generation through the USB interface to the host computer.
