Multi-Combined Series - Transformer DC Resistance Ratio (On-load) Tester
Transformer DC resistance ratio (on-load) tester is a highly efficient integrated solution tailored for the power industry, transformer manufacturing and field maintenance and other professional scenarios. The equipment innovatively realizes the completion of DC resistance and ratio (on-load) testing in one wiring, which significantly improves operational efficiency and effectively saves labor costs. It is especially worth mentioning that the instrument is equipped with the unique quantitative demagnetization function, which is especially suitable for the maintenance test of large transformers, and ensures accurate and efficient test performance in complex environments.
Excellent Direct Resistance Test Performance
Suitable for Yn, Y and △ type windings, it adopts the cutting-edge three-phase synchronous measurement technology, automatically calculates the three-phase unbalance rate, and provides a maximum test voltage of 28V and a test current of 20A, which meets the needs of the vast majority of transformer testing. Especially for large-capacity main transformers, the built-in magnetizing resistance function.
Full Turn Ratio Testing Capability
Widely support three-phase, single-phase and Z-type transformer ratio test operations, while including PT / CT ratio determination, polarity test and blind test mode, a full range of adapted to different types of transformers and their supporting equipment testing needs.
Advanced On-Load Tap-Changer Testing
In the face of on-load voltage regulator transformer, this tester innovatively realizes fully automatic control on the low-voltage side without manual intervention, and it can flexibly select 2A, 1A, 0.5A multi-step current output, which simplifies the workflow and improves the testing safety and accuracy at the same time.
Rigorous Security Protection Mechanism
Equipped with 380V power misconnection automatic protection system and grounding wire not connected to the alarm function, effectively eliminating equipment damage and personal safety risks caused by operational errors.
Humanized Interactive Experience
Adopting a 10.1-inch industrial-grade touch screen, combined with a one-button shuttle knob control design, it transforms the complex testing process into an intuitive and easy-to-use operation interface, which greatly enhances the user's operational convenience and comfort.
Efficient Data Management And Report Output
Built-in large-capacity storage space to save all the test results, support for rapid data export via U disk, and configured with a thermal printer to print the test report instantly, which is not only convenient for on-site recording, but also provides great convenience for later data analysis and processing.
