Electronic Transformer Calibrator Calibration System

Main Usage:
Meet IEC61850 the (-9-1 -9-2-9-2LE have been added) standard electronic
transformers verify; electronic check electronic transformer polarity and
delay; small signal output transformer check; parity of the merger of the
small-signal input unit; 0.05 0 ~ 7V output two precision voltage signal,
without l large voltage and high current can be; merger of small signal input
unit school experience (extended precision standard source module); able to
output a digital signal source (FT3 format), do not need to verify liter large
voltage and high current can support the FT3 input merged unit. (Extended
digital signal source module); electronic transformer output FT3 check
(Extended FT3 conversion module); to traditional transformer parity (the
extended analog signal conversion module).

Main features:
HENZ3-HR electronic transformer calibrator for electronic transformer to
meet IEC61850 (-9-1, -9-2,-9-2LE) standard output checksum. Check project
include: the ratio difference, phase difference, delay, polarity. At the same
time small signal input terminals, electronic transformer small signal output
part as well as the merger of the small-signal input unit check.

Main functions:
Using the traditional transformer calibrating device (BHE type) and Agilent
3458A Digital Multimeter
value transfer.
2. Use the built-in GPS or high stability the crystal output pulse
synchronization signal.
3. IEC61850 (-9-1, -9-2,-9-2LE) protocol packets full frame resolution
automatic analysis ASDU data,
Sampling points, all channel waveform diagram, no need to get caught you
can visually view all
channel data.
ST / SC dual fiber Ethernet interfaces and dual RJ45 Ethernet interface,
improve reliability, and
convenient access interface electronic transformer.
order quasi-synchronization algorithm makes non-synchronous sampling algorithm
error is
approaching zero.
6. 24Bit AD chip and 512 times oversampling technique, greatly expand the
bandwidth to improve the
accuracy.
7 multi-gear automatic switching and FIR filter to improve the dynamic range
and reduce the signal-
to-noise ratio.
Real-time display of the waveform, frequency, amplitude, phase, and other data
to facilitate
comprehensive analysis of transformer performance.
9. with IPC, 800 * 600 touch screen. More convenient operation.
10. with a powerful, easy operating software can be run on industrial computer
or laptop
11. Statistical ratio difference and phase difference between the mean, worse,
extrema, multiple error
data, a comprehensive test of the stability and linearity of the
electronic transformer.
12. Multiple harmonics analysis and electronic transformer harmonic accuracy
check.
13. throughout the testing process. Recording and playback.
14. drop-frame test, real-time statistics of dropped frames.
