The Automatic Digital Portable Power Transformer Turns Ratio Tester (TTR Meter) is engineered for turns ratio and voltage ratio testing of power transformers during production, at the semi-finished and finished stages, before commissioning of newly installed units, and as part of State Grid preventive testing regulations.
Traditional ratio bridges are cumbersome to operate, offer non-intuitive readings that require conversion, and only provide the ratio value of a single phase. The HZBB-I overcomes these limitations. It features a large-screen high-resolution LCD display with English menu prompts for convenient, intuitive on-site operation. It completes three-phase turns ratio testing in one pass, delivering fast testing speed and high accuracy.
