  • Product Features
    1. No need to boost the source, the standard transformer, the load box, can realize the field test voltage transformer ratio difference, the angle difference, the test result completely satisfies the national mutual inductor verification regulation.
    2. With polarity, ratio, connection check function; single testers can finish the measurement of voltage transformer error.
    3.  The CT Analyzer instrument adopts frequency conversion technology, digital processing, with strong anti-interference ability.
    4. The maximum voltage of the test process is not more than 4KV, and takes multiple protection measures to ensure personal and equipment safety and reliability.
    5. Instrument with a dual USB communication port, the instrument can be imported into the U disk internal data greatly facilitate the field data management.
    6. Automatic test data for the whole, and to determine whether the data is ultra poor, super bad data using anti black display, the data characteristics of the device is intuitive and clear.
