Main features:
(1) It combines the principle of the potential difference and advanced processing system; combines stability and intelligence; with high electric- pollution proof capacity, user-friendly, (the only finest ones all over the country)
(2) On-line measuring: it can be applied anywhere and then will show results
(3) Automatic judgment: however serious wrong operations are done; it will not cause damage of instruments and operators
Testing range automatically shifting switchover: according to levels of accuracy, it can automatically shift the testing range.
The key technical indexes:
(1) Measuring objects: PT CT YZ
(2) Instrument accuracy: level 1-2
(3) Measured instrument accuracy: level 10-0.01(can measure level-S current instrument transformer)
