Product description

Product Introduction
  This transformer capacity characteristic comprehensive testing instrument is mainly used to test the capacity of standard distribution power transformers under low voltage and low current conditions. It can also be used to test the no-load loss of transformers. The instrument features exquisite circuit design, unique ideas, superior performance, and powerful functions, fully meeting the requirements of on-site distribution power transformer capacity testing.
Main Features
  ◆ Can accurately measure the capacity of various transformers, passive measurement, convenient and accurate;
  ◆ Can measure the no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance of various types of transformers;
  ◆ Can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), and current correction (short-circuit test under non-rated current conditions). Operators only need to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected results. This is very suitable for units that do not have the conditions for performing short-circuit tests on slightly larger capacity transformers;
  ◆ Allows external connection of voltage transformers and current transformers for extended range measurement, allowing measurement of any parameter of the tested item.
