HZBB-10B-I Portable Automatic Transformer Turns Ratio Tester Digital TTR Meter
Product Description
Performance:
HZBB-10B-I intelligent tester of Transformer Ratio and Connection Groups adopts popular ARM
processor, 168M frequency, 128M memory available to be extended to 4G memory card. The LCD screen adopts 7-inch high-definition color touch screen, combined with emwin display, making the tester interface simple and user-friendly in full touch screen and non-keyboard operation. The tester supports database and can be exported from the USB drive or through the data cable to the background computer.
Elaborate and compact design, unique thinking, makes the tester superior and powerful with small size and light weight. The tester uses a programmable signal source, can output single-phase, two-phase or three-phase standard Sine signal or high-frequency Sine signal, with adjustable output phase frequency. It is especially suitable for special transformers such as Z-type transformers, rectifier transformers, Scott or anti-Scott transformers, etc. The tester adopts the new algorithm developed by our company to measure the ratio of three-phase transformer and ensure the measurement accuracy without adjusting the balance of the three-phase power supply. Therefore, the transformer ratio and wiring method can be measured in about 3 seconds.
Turns Ratio Tester Parameter:
1. The ground terminal or the ground wire in the power cable should be grounded reliably.
2. Please note that the four-color test wires at the high-voltage side in yellow, green, red and black correspond respectively to the transformer A, B, C, N terminals. The three-color test wires at the low-voltage side in yellow, green and red correspond respectively to the transformer a, b, c, n terminals. Be sure to make correct connections.
3. When testing the Scott transformer, the high voltage side is the same as the above, low-voltage side a, β, n correspond to a, b, c terminal.
For single-phase transformer, high-voltage side A, X correspond to A, C terminals, low-voltage side a, x corresponds to a, c terminals.
4. For general Y / y, Y / d, D / d, D / y, ZN / y, ZN / d normal connection group measurements, connection to the neutral point N terminal is not needed. For single-phase transformer measurements, please use the yellow, green test clips at high-voltage side and the yellow, green test clips at low-voltage side.
5. Please enter correct setting parameters before test. The group label and the measured transformer must be consistent. If not sure, choose unknown to be measured by the tester automatically.
6. If you the rated ratio is not put in, results only show the measured ratio value, and do not show the error.
7. To make self-test, please use the built-in output and externally connect standard instrument. Make comparisons between the first and second voltage measurements to check its accuracy.( The accuracy cannot be confirmed in measuring range as the nonlinearity of the Potential Transformer.)
Ratio measurement range: 0.8-5000(0.8-20000 for Customization)
