HZTTR80A Transformer Turn Ratio Tester

Panel Description

1. Grounding Terminal: Before conducting any tests, please safely ground the grounding terminal to avoid the risk of electric shock.

2. Power Socket and Switch: The power input port for the entire device, used to connect or disconnect the test power supply.

3. High-voltage side connection terminals: There are three-color (yellow, green, red, and black, with the black one being counted as part of the color indication context here for understanding the connection mapping, though technically it's a single additional color column beyond the three primary phase colors) binding posts, corresponding to connection with the A, B, C, N phases of the high-voltage side of the transformer being measured.

4. Low-voltage side connection terminals: There are three-color (yellow, green, red, and black, similarly, the black one is included in the context for connection mapping explanation) binding posts, corresponding to connection with the a, b, c, n phases of the low-voltage side of the transformer being measured.

5. High-Voltage Side Terminals: Yellow, green, and red terminals for connecting to the A, B, and C phases of the high-voltage side of the transformer under test.

6. Low-Voltage Side Terminals: Yellow, green, and red terminals for connecting to the a, b, and c phases of the low-voltage side of the transformer under test.

7. RS232 Communication Interface: Interface for computer communication.

8. Printer: Prints test results.

9. USB: Connects to a USB flash drive for data export.

10. Display Screen: 7-inch high-definition color touchscreen LCD with adjustable backlight for displaying the operation menu and test results.

Troubleshooting and Maintenance

If any abnormalities occur during the use of the tester, please follow the steps below for troubleshooting:

1. If the measurement data is abnormal, please check if the wiring is correct. If it is still abnormal, you can perform a self-test using the following method. The wiring is shown in the figure below:After connecting the wires, select any three-phase connection method for testing. If the measured value is approximately 1.0000, the instrument is functioning normally; otherwise, there is an issue with the instrument. If no shorting wire is available, you can also short-circuit the high-voltage side yellow, green, and red wire clamps to the corresponding low-voltage side yellow, green, and red wire clamps.

2. If the tester does not respond when turned on and the display screen is not lit, please check if the power fuse inside the panel is blown.

3. If it is confirmed to be an internal fault of the tester, please contact our company immediately, and we will resolve it as soon as possible.
