Transformer Ratio Bridge Tester - Yangzhou Dary
Dary Electric recommends for you
Features
1. The Transformer Ratio Bridge Tester adopts the complex current method to measure the ratio and phase angle of each winding of CVT. The test results are highly accurate and facilitate automated measurement.
2. The instrument uses frequency conversion technology to eliminate 50Hz power frequency interference on site, ensuring reliable data even in strong electromagnetic interference environments.
3. The instrument features a large-screen LCD display, and the test process is guided by Chinese menu prompts, making it intuitive and easy to operate.
4. The instrument is easy to operate, and the measurement process is controlled by a microprocessor. Once the appropriate measurement mode is selected, data measurement can be automatically completed under microprocessor control.
5. Integrated design with built-in standard capacitor and high-voltage power supply, convenient for on-site testing and reducing on-site wiring.
6. Ground protection function: when the instrument is not grounded or poorly grounded, it will not enter the normal program and will not output high voltage. Overcurrent protection function: the instrument will not be damaged in case of short circuit or breakdown of the test object.
7. Electric shock protection function: if the operator accidentally gets an electric shock, the instrument will immediately cut off the high voltage to ensure the safety of the test personnel.
Equipment Introduction
The TPHGC-TYD CVT Ratio Tester is mainly used for measuring the ratio of each winding of capacitive voltage transformers. This instrument breaks through the traditional ratio bridge measurement method, adopting variable frequency power supply technology, using microcontrollers and modern electronic technology for automatic frequency conversion, analog-to-digital conversion, and data computation; it has strong anti-interference capability, fast test speed, high accuracy, full automation and digitalization, and simple operation; the power supply uses a high-power switching power supply, outputting 45Hz and 55Hz pure sine waves, automatically boosting voltage to provide 10kV voltage; it automatically filters out 50Hz interference, suitable for on-site testing in substations and other environments with high electromagnetic interference.
