The field test instrument of capacitive voltage transformer can measure the actual error under the condition of high voltage under the condition of low voltage. A single device can meet the measurement of the error of capacitive voltage transformer in the field. It can cover the measurement of all kinds of capacitive voltage transformers. In the design of the instrument, some new ideas and technologies are introduced, including different frequency power supply technology, general platform technology, voltage simulation load, internal high accuracy voltage transformer and self-boosting power supply. Users feel more convenient, fast and efficient when using the instrument.
