NDXCY-IV inter-frequency anti-interference line parameter tester

　　Reference standard: GB50150-2006, DL/T1119-2010.

 

　　Features:

　　● Separate the main unit and the power supply on the basis of the original all-in-one machine, which greatly facilitates the use, transportation and after-sales. It is the smallest and lightest of the same domestic products; it provides the most simple and convenient test method for the test;

　　● Strong anti-interference ability, the instrument's internal variable frequency power supply module provides instrument measurement output power, the frequency can be changed to 45Hz or 55Hz, and digital filtering technology is used to effectively avoid the various power frequency interference signals on the site, so that the instrument can realize High precision, accurate and reliable measurement;

　　● Accurate and fast, the instrument uses a professional DSP fast digital signal processor as the processing core, which greatly improves the computing processing capability of the instrument itself under the premise of ensuring accurate measurement data;

　　● The external wiring is simple. The positive sequence impedance, zero sequence impedance, positive sequence capacitor, and zero sequence capacitor can complete all measurements only once when the test terminal needs to access the down line of the tested line.
