CTA-1000 frequency conversion transformer TESTER

      CTA-1000   variable frequency transformer comprehensive test instrument is a new-generation innovative CT and PT test instrument developed on the basis of the traditional transformer voltage regulator, booster and current riser based on the transformer volt-ampere characteristic variable ratio polarity comprehensive test instrument, which is widely listened to the opinions of users, after a lot of market research and in-depth theoretical research. The device adopts high-performance DSP and FPGA and advanced manufacturing technology, which ensures stable and reliable product performance, complete functions, high degree of automation, high test efficiency, and is in the leading level in China. It is a professional testing instrument for transformer in the power industry.

     It mainly has the following functions and features:

     1.comprehensive functions, satisfy all kinds of  CT  (such as: protection, metering, TP) excitation characteristics (i.e., volt-ampere characteristics), variable ratio, polarity, the secondary winding resistance, secondary load, poor contrast and the Angle of test requirements, and can be used for all kinds of PT electromagnetic unit excitation characteristics, strain ratio, polarity, secondary winding resistance and contrast test.

     2.the current transformer without the standard current transformer, inverter, load cases, regulating control box and high-current conductor, using a very simple test wiring and realization of current transformer test operation, greatly reduce the working intensity and improves the work efficiency, convenient to carry out the transformer on-site verification work.

     3.The variable ratio difference and Angle difference can be accurately measured. The maximum allowable error of the difference is 0.1%, and the maximum allowable error of the Angle difference is 5min.
