Our company innovatively developed the ZXRY-10A transformer on-load direct resistance tester. We only need one set of equipment, which can complete the test of two projects and do not need to dismount the test line frequently, thus greatly improving the work efficiency and saving the user cost. The traditional test method for the two test items is split test, which requires a direct resistance test and an on-load tap switch tester. Because they are two independent instruments, each instrument is equipped with a special test line, which requires separate wiring and testing, so that the work efficiency is greatly reduced.
1. One connection, can complete the direct resistance test and load test two test items.
2. Direct resistance test function, for type Yn, type Y and type △ winding can be tested by three-phase measurement method, and calculate the three-phase unbalance rate; The highest output voltage of the test power supply is 28V and the highest output current is 20A, which can meet the test requirements of most transformers. Designed for high voltage grade, large capacity main transformer magnetic test function, so that the direct resistance test speed greatly accelerated.
3. On load test, low voltage side without manual short-circuit, automatic instrument control; Maximum output current up to 2A, suitable for smaller transition resistance measurement.
4. The 380V power supply is misconnected with the automatic protection function and the grounding wire is not connected with the alarm function, to ensure your safety.
5. Industrial 10.1-inch large display, fresh and simple display style design, full touch combined with one-button shuttle operation, for you to create a comfortable and convenient human-computer interaction experience.
