Inter-frequency line parameter tester

Product Parameter

Product Feature And Application

1.The instrument is equipped with a 7-inch large touch color display screen and a super large full-touch operation interface. It is easy to operate. All operation steps are displayed in Chinese menus, and each step is very clear. Operators do not need additional professional training to use it. With just a gentle touch, the entire measurement process can be completed. It is currently a very ideal intelligent measurement device.

2. It is the smallest in volume and light in weight, providing the simplest and most convenient testing method for experiments.

3. All the measurement processes of the instrument only require connection to the 220V mains voltage, solving the trouble of inconvenient on-site connection to 380V voltage in the existing measurement methods.

4. The instrument is equipped with a unique anti-induced voltage circuit inside, ensuring that it can withstand higher induced voltages (with an anti-induced current of up to 30A) and operate normally under a high induced voltage of 10,000 volts.

5. It has strong anti-interference ability. The measurement output power of the instrument is provided by the built-in frequency conversion power supply module inside the instrument. The frequency can be changed to 47.5Hz / 52.5Hz, 45.0Hz / 55.0Hz, 57.5Hz / 62.5Hz, 55.0Hz / 65.0Hz, and digital filtering technology is adopted. It effectively avoids various power frequency interference signals on site, enabling the instrument to achieve high-precision, accurate and reliable measurement.

6. Precise and fast, the instrument adopts a professional fast digital signal processor as the processing core inside, which greatly enhances its own computing and processing capabilities while ensuring the accuracy of the measurement data.

7. The external wiring is simple. The positive sequence impedance, zero sequence impedance, positive sequence capacitance, and zero sequence capacitance only need to be connected to the test leads of the line under test once at the test end to complete all measurements. It has solved the problems existing in the current testing methods, such as the cumbersome process of switching test wiring, anti-interference, stability and accuracy. Avoid the harm to the laboratory personnel caused by the induced voltage when changing the wiring.

8. The instrument is equipped with a calendar chip and a large-capacity memory inside, which can save the test results in chronological order. Historical records can be viewed at any time and printed out.

9. The instrument data can be exported via a USB flash drive, viewed and managed on any PC, and can be made into a work report.

10. The instrument is specially designed with a grounding detection function inside to determine whether the instrument is well grounded on site. If the grounding is loose or not connected at all, the instrument will automatically determine and prohibit the operator from operating it to ensure personal safety and protect the use of the instrument.
