HGQA-12C multi-bit CT transformer calibration station

HGQA-12C automatic transformer multi-pole calibration device is also called transformer calibration platform, transformer calibration device, transformer calibration device, transformer detection device, automatic transformer multi-pole calibration device is our company's new

The new generation of intelligent transformer calibration platform developed by the company has faster calibration speed, more accurate test data, better stability and more complete protection functions. The device consists of an intelligent transformer calibrator, voltage and current load box, electric

Sub-source control cabinet, multi-position transformer test bench, etc. are composed of several parts.

       The operator sets the main parameters such as the type, transformation ratio, accuracy level, secondary load, power factor, and position of the tested transformer through the transformer error management software, and the primary upflow process (about 3 minutes)

) The error data of 12 current transformers with the same ratio can be measured and stored in the database.

       The device can automatically verify various high-voltage current transformers, voltage transformers, combined transformers and metering boxes in accordance with national verification regulations. It is ideal for transformer verification by power systems and other metrology regulatory agencies.

equipment.

Multi-pole instrument transformer verification device Features —— Summarize

        1. The device has three test modes: online automatic, stand-alone automatic, and stand-alone manual.

        2. One-time up-current process (3-5 minutes) completes the measurement of 12 current transformers, realizing the real speed calibration function

        3. The program-controlled electronic source is adopted, and the fixed point is rapid and accurate, which overcomes the shortcomings of traditional electrician voltage regulators such as large noise and mechanical wear.

        4. During the test, the standard transformer primary and secondary wiring, voltage and current load box are fully automatic and automatically switched, without manual shifting.

        5. Stations can be arbitrarily selected for verification, and the test stations, standard transformer wiring, power factor, and secondary load can be displayed simultaneously.

        6. It can also be used as a power frequency and triple frequency withstand voltage test bench for transformer withstand voltage test.

        7. With overvoltage, overcurrent, and dial indicator protection, various protection functions such as phase loss, wrong transformation ratio, wrong polarity and excessive error during the test.

        8. The error management software device can be connected to the seamless ports of the State Grid, China Southern Power Grid, and local power grid marketing systems.
