Product Introduction

During the production process of semi-finished and finished electrical transformers, prior to the operation of newly installed transformers, and in accordance with the State Grid's preventive testing procedures, it is required to regularly test the turns ratio or voltage ratio of operating transformers. Traditional ratio bridges are cumbersome to operate, the readings are not intuitive, and necessary calculations must be performed. The test results only provide the value of a single-phase ratio.

The LDBBZ-1000A Transformer Ratio Tester overcomes the drawbacks of traditional transformer ratio bridge testing. It features a large, high-resolution LCD screen for on-site convenience, with Chinese menu prompts for easy and intuitive operation. It completes three-phase ratio testing in one go, offering fast testing speed and high accuracy.
