1. RS025-Y voltage transformer error tester is integrated with
functions of measuring voltage transformer error by method of error
characteristics simulation and measuring voltage transformer error
by method of potential difference, facilitating metering devices to
conduct field verification on site.
2. There is no need to use a standard voltage transformer, voltage
booster, load box and voltage regulating control box to verify
voltage transformer on site, and extremely simple test wiring and
operation are used to verify electromagnetic voltage transformer,
which greatly reduces working intensity and improves working
efficiency, and facilitate to develop field verification of
transformer.
3. RS025-Y voltage transformer error tester is equipped with
standard voltage transformer with the same transformation ratio as
tested voltage transformer, and its precision degree is 0.02 class,
which can accurately measure transformation ratio and no-load error
of the testing voltage transformer. Then combine with impedance and
admittance testing results to calculate transformer error.
4. Wide measurement range, able to expand to 6kV/100V-220kV/100V.
5. With the functions of testing transformation ratio, internal DC
resistance and voltage load box of voltage transformer.
6. With function of testing dual-winding voltage transformer, with
two load boxes.
7. It has 640×480 high-resolution large-screen LCD display,
humanized interface and operation design. And a touch screen is
used to facilitate operation which makes operation more convenient
and faster.
8. The accurate software algorithm has further improved accuracy of
measuring data.
9. Able to intelligently judge external wiring state, point out
wiring error, transformation ratio, polarity error, etc.
10. Automatically round off testing data, determine whether it
exceeds out-of-tolerance which will be displayed through
counter-black, which makes transformer data characteristics
intuitive and clear.
11. Directly issue field verification conclusion of being qualified
or not.
12. Large-scaled memory unit can preserve 1000 sets of field
testing data.
13. Equipped with printer, able to print testing data on site.
14. Engineering plastic mold machine box has vibration resistance
and pressing resistance, which ensures safety of operators and
equipment for field high-voltage test.
