Voltage Ratio, Ratio Error Digital Transformer Turn Ratio Meter

I. Product Introduction & Features:

In the production, handover, and maintenance of power transformers, conducting a transformer ratio test is an essential step. This test helps ensure the quality of the transformer during manufacturing and in its operational life, preventing issues such as turn-to-turn short circuits, open circuits, connection errors, internal faults in the regulating switch, or contact failures. The automatic transformer ratio tester developed by our company meets on-site requirements, making operations simpler, with full functionality, stable and reliable data, and faster testing speeds. It caters to various large and small transformer testing needs.

• Easy to operate
• Large ratio measurement range (1-10000)
• Powerful, capable of testing single-phase or automatically testing three-phase windings, with arbitrary selection of connection groups and complete measurement of AB, BC, CA parameters including ratio, error, and connection group
• Quick measurement (three-phase test at once only takes 10 seconds)
• Automatically cuts off the test power after one test is completed
• Data can be set, with results automatically saved and previous data viewable
• Test load transformers by inputting the ratio just once
• Portable and suitable for field work
