Automatic Transformer Voltage and Turns Ratio Test Set/TTR Test

I. Product Introduction & Features:

In the production, handover, and maintenance of power transformers, transformer ratio testing is an essential step. It helps ensure the quality of the transformer during both manufacturing and operation, preventing issues such as turn-to-turn short circuits, open circuits, connection errors, internal faults in tap changers, or contact failures. The automatic transformer ratio tester developed by our company meets on-site requirements, making operations more straightforward, with full functionality, stable and reliable data, and faster testing speeds. This device is suitable for various types of transformer tests, whether large or small. Features: 1. Easy to operate. 2. Large ratio measurement range: 1-10000. 3. Powerful design that supports single-phase and three-phase winding tests. It allows users to choose any connection group and fully measure AB, BC, CA three-phase parameters including ratio, error, and connection group. 4. Fast measurement (three-phase test only takes 10 seconds). 5. Automatically cuts off the test power after one test is completed. 6. Saves measurement results automatically and allows viewing of previous data. 7. Tests load transformers by inputting the ratio just once. 8. Portable and ideal for field work.
