Product Features
     1. There is no need for voltage booster, standard transformer and load box. The principle of voltage transformer load curve extrapolation is adopted. The test results fully meet the national instrument transformer verification regulations.
     2. A single tester can measure the errors (ratio difference and Angle difference) of GIS electromagnetic voltage transformer (PT) and capacitive voltage transformer (CVT). At the same time, it can measure the partial voltage ratio of CVT, partial voltage capacitance, intermediate PT ratio, intermediate voltage, dc resistance, etc.
     3, with polarity, change ratio, wiring inspection functions.
     4. Complete all the wiring tests in one time, improve work efficiency, avoid personal and instrument damage caused by operation errors, and ensure safety.
     5. It has the characteristics of fast test speed, large amount of information processing and large storage capacity (millions of data can be stored). It has 16 gigabytes of memory and can store millions of data sets.
     6. The tester adopts frequency conversion technology and digital processing, with strong field anti-interference ability.
     7. The maximum voltage during the test shall not exceed 4kV, and various protective measures shall be taken to ensure personal safety and equipment safety and reliability.
