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.

Specification

Multi-Scenario Compatibility Design

1. Supports five three-phase connection methods (DY, DD, YD, YY, ZN) and single-phase connection, covering mainstream transformer types in power systems;

2. Compatible with dual standards of IEC 60076 (displays three-phase voltage ratio) and IEEE (displays turns ratio), adapting to test specifications in regions such as the EU and North America;

3. Can be used in scenarios such as substation maintenance, transformer factory inspection, and voltage transformer calibration without replacing test equipment.

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.
