w950i Transformer Turns Ratio Tester
In the reference materials, no information was found regarding the transformer turns ratio tester with the specific 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 learning about this ZSBC-9500 or similar transformer turns ratio testers available on the market, they typically possess the following core functions and features:
1. Core Functions and Blind Testing Capability
Primarily used for accurately measuring the turns ratio, voltage ratio, and connection group of power transformers and voltage transformers. Many advanced models support a "blind test" 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 Range of Equipment Adaptability
In addition to conventional three-phase and single-phase transformers, they can also accommodate testing requirements for various special transformers, such as Z-type transformers, rectifier transformers, electric furnace transformers, non-integral phase-shifting transformers, traction transformers, and Scott/Inverse Scott transformers, among others.
3. Automated and Intelligent Operation
Modern turns ratio testers typically incorporate a built-in digital synthesis three-phase standard sine wave signal source, capable of automatically outputting test voltage and synchronously collecting 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 intuitively display vector diagrams to help determine the correctness of wiring.
4. Data Storage and Portability
The instruments are mostly designed with built-in rechargeable batteries, making them convenient for outdoor field use without access to the mains power supply. They also feature large-capacity data storage that does not lose data upon power failure (some can be expanded to store thousands of data sets), and test results can be transferred to a computer via USB flash drive or RS232 interface, enabling data printing and computerized management through backend software.
5. Safety and Protection Mechanisms
The equipment typically comes with 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 indeed need to find information on the specific instrument "w950i", it is recommended that you verify the complete model number on the equipment nameplate, or directly consult the paper manual that came with the device, or contact the equipment manufacturer to obtain the most accurate technical parameters and operating instructions.
