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).
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.
