In the production, user handover, and maintenance testing of power transformers, the transformer ratio test is a mandatory item. This effectively supervises the quality of transformer products during factory delivery and use, preventing inter-turn short circuits, open circuits, connection errors, internal faults in tap changers, or contact faults.
The GHBC-I fully automatic ratio and group tester developed and produced by our company, based on the original model and according to users' on-site usage requirements, makes operation more convenient, functions complete, data stable and reliable, and greatly improves testing speed. It meets the needs of ratio testing for various large, medium, and small transformers.
Product aliases: Ratio tester, Ratio and group tester, Fully automatic ratio and group tester, Transformer ratio and group tester, Automatic ratio and group tester
1. Chinese menu prompts, simple and convenient operation.
2. Wide ratio measurement range: 1-9999.9
3. Powerful functions: It can perform single-phase measurement and also achieve automatic testing of three-phase windings. The connection group can be selected arbitrarily, and parameters such as ratio, error, and connection group for AB, BC, and CA phases can be measured in one go.
4. Fast measurement speed.
5. After one measurement is completed, the test power is automatically cut off.
6. Set data and measurement results are automatically saved, and previous data can be viewed.
7. For testing on-load transformers, only one ratio input is required.
8. Portable and suitable for field operations.
