Effect
- Transformer is an important component of the power system, which converts high voltage and high current into low voltage and low current for measurement, protection, and control. In order to ensure the normal operation of the transformer, it is necessary to conduct regular inspections and tests, and the transformer volt ampere ratio polarity comprehensive tester is an important tool to complete this task.
Advantage
- Only simple numerical settings are needed: set the rated parameters of the transformer. The instrument will automatically record data throughout the entire process and calculate and display the polarity and volt ampere characteristic curves of the transformation ratio, eliminating the tedious labor of changing wires, manually adjusting voltage, manually recording, organizing, and drawing curves. The use of extremely simple operation and wiring methods to achieve the measurement of transformers greatly reduces work intensity and improves work efficiency, making it convenient for on-site transformer measurement work; Quick, simple, precise, and convenient.
