Three phase ratio group tester

Variable ratio group testerUsing a variable ratio bridge to measure the transformation ratio of a transformer is cumbersome to operate and has a narrow measurement range, which is no longer suitable for the fast-paced and high-efficiency requirements of modern measurement. Therefore, a new generation of transformer ratio tester has been developed using modern electronic technology. It has a small volume, light weight, high precision, and good stability. It adopts a large screen Chinese character display, menu operation, and user-friendly interface. The variable ratio group can be tested in one go. The transformer ratio tester is an ideal testing instrument for the power industry sector.

1、 Main features

High precision measurement: capable of providing high-precision variable ratio measurement results. For example, some models of testers can achieve a measurement accuracy of 0.2% within the range of variable ratios 1-500; Within the range of 501-2000, the measurement accuracy can also be maintained at 0.5%.

Wide range: This type of tester typically has a wide measurement range, such as a ratio range of 1-2000, and can automatically switch ranges to meet the testing needs of different transformers.

Easy to operate: Testers generally use large screen LCD Chinese character display and menu operation, with a friendly interface that makes the operation process more simple and intuitive.

Comprehensive functions: In addition to basic ratio measurement, it can also perform multiple functions such as group testing, wiring confirmation, and short circuit detection.

Data storage and printing: Test results can be automatically stored and exported or printed through a USB flash drive, facilitating subsequent data analysis and processing.

2、 Working principle

　　Variable ratio group testerThe working principle of is mainly based on the principles of field-effect transistors and transformer ratio converters. Field effect transistors are used to control the ratio of input voltage to output voltage, achieving measurement of transformation ratio. The transformer ratio converter is responsible for converting the input voltage and output voltage of the transformer into digital signals to achieve accurate measurement.

3、 Application Fields

It plays an irreplaceable role in the industrial field related to transformers. It is widely used in power plants, substations, steel plants, railways and other fields to test the winding turns, transformation ratio, phase difference, circuit resistance and other parameters of transformers, thereby ensuring the normal operation of transformers.

4、 Operation precautions

Safety protection: Before operation, operators must wear personal protective equipment such as safety helmets, insulated gloves, etc. to prevent electric shock and other accidental injuries.

Equipment grounding: Ensure good grounding of the equipment to reduce the risk of electric shock.

Check equipment status: Before operation, check the working status of the equipment to ensure that it is in normal working condition and there is no obvious damage or malfunction.

Follow the operation manual: Carefully read the operation manual and follow the operation steps in the manual to avoid arbitrary operation or attempting untrained operation.

5、 Maintenance and upkeep

To ensure the accuracy and service life of the equipment, regular maintenance and upkeep should be carried out. This includes keeping the equipment clean, regularly checking whether the connection wires of the equipment are loose or damaged, and regularly calibrating the equipment to ensure measurement accuracy.
