HZBB -10 B变压器便携式手持式变比测试仪表

In the production of semi-finished and finished products using power transformers, before a new transformer is put into operation, and in accordance with the national ministry's preventive testing procedures, it is required to conduct a transformer turn ratio or voltage ratio test. This test allows for the verification of the transformer's turn ratio, the condition of the tap changer, the presence of turn-to-turn short circuits, and whether the transformer can run in parallel.The HZBB-10B intelligent transformer ratio group tester, which uses a new algorithm developed by our company, can measure the three-phase transformer ratio without needing to adjust the balance of the three-phase power supply, ensuring measurement accuracy. As a result, the test is fast, and the ratio and wiring mode can be measured in approximately 3秒.
