Quick Test Noise Reduction 3-Phase TTR Meter Digital Transformer Turn Ratio Tester TTR Tester
Product Description
Quick Test Noise Reduction 3-Phase TTR Meter Digital Transformer Turn Ratio Tester TTR Tester
Transformer Turns Ratio Tester
GDBC-901B is a professional tester by Chongqing Gold Mechanical&Electrical Equipment Co.,Ltd. ,integrating high-precision measurement and comprehensive safety protection, supporting portable operation and on-site printing, meeting professional needs of the power industry.
Core Precision Guarantee Technology
Adopts a three-phase electronic AC voltage source with sine wave distortion <1%, avoiding municipal power noise interference, and test repeatability better than 0.05%;
Synchronously collects high-voltage side output and low-voltage side induced voltage, accurately corresponds through phase matching, and controls turns ratio error within 1-1000±0.2% and 1000-10000±0.5%;
Phase angle test range is 0-360° with error <0.5°, which can accurately judge the phase consistency of transformer windings and assist in evaluating winding quality.

Experimental results
Portable Battery Life & Efficient Operation
Built-in 12V/15000mAh large-capacity lithium battery, working over 10 hours on a single charge, meeting off-grid scenarios such as outdoor substations and remote power plants;
Body size 400×350×200mm, weight <10kg, with a hidden handle (reasonably extended based on portability needs), portable by a single person;
Touch screen operation + virtual keyboard input, making parameter setting intuitive and efficient, reducing on-site operation error rate.
Data Interconnection & Report Management
USB interface supports connecting to a PC to batch upload 200 groups of historical test data, avoiding manual recording errors;
Automatically generates Word format reports, including key information such as equipment number, test time, and turns ratio error, facilitating customer acceptance and data archiving;
Built-in micro printer allows on-site report printing after testing, no need to rely on external equipment, improving on-site operation efficiency.
