UHV-740 Capacitive Voltage Transformer Field Calibration Instrument

• 1、No boost source, standard transformer, load box, using the principle of voltage transformer load curve extrapolation method, a single instrument can realize the field test GIS electromagnetic voltage transformer (PT) and capacitive voltage transformer (CVT) 20%, 50%, 80%, 100%, 120% of the full load and light load of the specific difference and Angle difference. The test results fully meet the national instrument transformer verification regulations.

• 2、A single tester can complete the measurement of GIS electromagnetic voltage transformer (PT) and capacitive voltage transformer (CVT) error (ratio difference, Angle difference). At the same time, it can measure CVT capacitance partial voltage ratio, partial voltage capacitance, intermediate PT ratio, intermediate voltage, DC resistance and so on.

• 3、With polarity, ratio, wiring check function.

• 4、Complete all tests at one time, improve work efficiency, avoid operating errors to personal and instrument damage, to ensure safety.

• 5、It has the characteristics of fast test speed, large processing information and large storage capacity (can store millions of data). The memory is 16GB and can store millions of data sets.

• 6、The tester adopts frequency conversion technology and digital processing, and has strong anti-interference ability in the field.

• 7、The maximum voltage of the test process does not exceed 4kV, and various protective measures are taken to ensure personal safety and equipment safety and reliability.

• 8、The test procedure is simple to operate.

• 9、Capacitive voltage transformer field calibrator adopts WINCE system, humanized color touch screen operation, but also can use the mouse to operate the instrument, the human-machine interface is intuitive and convenient.

• 10、The capacitive voltage transformer field calibrator has dual USB communication port, which can import the internal data of the instrument into the U disk greatly facilitate the field data management. The instrument can also be operated with the mouse.

• 11、The connection diagram attached to the capacitive voltage transformer field calibrator is simple and intuitive, and the control connection can be used on site to ensure that the test connection is correctly completed at one time and reduce the preparation time.
