w950i Transformer Turns Ratio Tester
In the reference materials, no information was found regarding the transformer turns ratio tester specifically model "w950i". However, the materials mention a similar device with a model number containing "9500" - the ZSBC-9500 Special Transformer Turns Ratio and Group Tester.
If you are interested in this ZSBC-9500 or similar transformer turns ratio testers available on the market, they typically have the following core functions and features:
1. Core Functions and Blind Measurement Capability
Mainly used for accurately measuring the turns ratio, voltage ratio, and connection group of power transformers and voltage transformers. Many advanced models support the "blind measurement" function, which can accurately measure the turns ratio, group number, and phase angle even without knowing any nameplate parameters of the transformer under test.
2. Wide Device Adaptability
In addition to conventional three-phase and single-phase transformers, they can also adapt to the testing needs of various special transformers, such as Z-type transformers, rectifier transformers, electric furnace transformers, non-integral phase-shifting transformers, traction transformers, and Scott/Reverse Scott transformers, etc.
3. Automated and Intelligent Operation
Modern turns ratio testers typically have a built-in digital synthesis three-phase standard sine wave signal source, which can automatically output test voltage and synchronously collect signals from the high and low voltage sides. The equipment is equipped with a large-screen true color LCD display and a full Chinese graphical interface, which can visually display vector diagrams to help judge the correctness of wiring.
4. Data Storage and Portability
The instruments mostly adopt a built-in rechargeable battery design, making them convenient for outdoor field use without mains power. They also have large-capacity data storage that does not lose data on power failure (some can be expanded to store thousands of sets of data), and test results can be transferred to a computer via a U disk or RS232 interface, with background software for data printing and computerized management.
5. Safety and Protection Mechanisms
The equipment usually has comprehensive protection functions, such as high-low voltage reverse connection protection and output short-circuit protection, to prevent equipment damage or safety accidents caused by wiring negligence.
If you really need to find information on the specific instrument "w950i", it is recommended that you check the complete model number on the equipment nameplate, or directly consult the paper manual that came with the equipment, or contact the equipment manufacturer for the most accurate technical parameters and operating instructions.
