Digital ratiometer HZBB-10B-I

for transformers

A Transformer Turns Ratio (TTR) tester is a specialized instrument used to measure the turns ratio of transformers, which is essential for ensuring their proper functionality and reliability. The turns ratio is the relationship between the number of turns in the primary winding and the number of turns in the secondary winding of a transformer. Accurate measurement of this ratio is crucial for assessing transformer performance, diagnosing faults, and ensuring compliance with industry standards. TTR testers are crucial for measuring the turns ratio of transformers, ensuring their reliability and performance. Huazheng Electric Manufacturing (Baoding) Co., Ltd. has developed advanced TTR testers,which offers precise measurements, user-friendly interfaces, and protective features. The device can perform simultaneous three-phase tests, enhancing efficiency and accuracy. With a focus on quality and innovation, Huazheng Electric is a leading manufacturer in the electrical testing industry, providing essential tools for maintaining reliable electrical infrastructure. 1.It can automatically measure the transformer ratio for both three-phase and single-phase transformers, and calculate the ratio error. 2.The number and polarity of the transformer connection group can be measured, and the secondary wiring vector diagram is displayed. This is intuitive, and the instrument has a self-calibration function. Based on the self-calibration results, it can distinguish between a faulty test line or instrument.
