Introduction:

The dual CPU architecture is used in the kernel of the verification system, and the function is strong, and the bandwidth is greatly expanded with 24BitAD chip and 512 times over sampling technology, and the measurement accuracy is improved. At the same time, the dynamic range and signal to noise ratio are improved by using multi file automatic switch and FIR filter. Use LabView development management software, beautiful interface, easy to use. The power supply and the sampling input adopt a lot of electromagnetic compatibility measures, which can adapt to the complex field test environment. Using the portable design scheme, convenient laboratory and field test.

Main purpose:

To meet the IEC61850 (-9-1, -9-2, -9-2LE) standard for electronic transformer check; check the polarity of the electronic transformer and the delay time; check on the small signal output of electronic transformer; small signal input to the merging unit check; precision voltage signal can be output two 0.05 level 0~7V, without high voltage and large current can rise; small signal input to the merging unit check (extended precision standard source module); can output digital signal source (FT3) format, without the need for high voltage and large current can rise to support the merging unit FT3 input check. (expansion of digital signal source module); can the FT3 output of electronic transformer calibration (extended FT3 conversion module); to check (extended analog signal conversion module of traditional transformer)

Main features:

XL-807 electronic transformer calibration instrument is mainly used in the -9-1 (-9-2, -9-2LE, IEC61850) standard output of electronic transformers for verification. Check items include: ratio difference, phase difference, delay, polarity, etc.. At the same time, a small signal input terminal can be configured to check the small signal output of the electronic transformer and the small signal input of the combined unit for verification, etc..
