Huazheng HZTTR80A Portable Transformer TTR Tester Supplier

The HZTTR80A Transformer Ratio Test Device is a fully automatic tester. It integrates testing functions for turn ratio, voltage ratio, vector relationship, winding connection, polarity, tap position, and excitation current. This tester is a lightweight and portable instrument. Both the tester and its accessories are housed in a multi-functional engineering plastic case that is resistant to cold, heat, moisture, and shocks, making it convenient for field tests. This test device can be used to test single-phase and three-phase transformers, both with and without taps. The instrument can be controlled using a dedicated app that is downloaded onto an Android phone or tablet. This allows for the storage and upload of test data for easy review.

Functional Characteristics

1. Capable of PT ratio and polarity testing.

2. Equipped with blind test function to accurately measure the transformer's ratio and connection group when the connection group of a three-phase transformer is unknown.

3. Capable of testing autotransformers, Z-type transformers, and phase-shifting transformers.

4. Added tap mode settings to accommodate transformers with high voltage at high tap positions and low voltage at high tap positions.

5. Added low-voltage side tap settings to accommodate transformers with taps on the low-voltage side.

6. Graphical display settings for more intuitive readings.

7.Simultaneous measurement of three-phase ratios during three-phase transformer testing for faster testing speed.

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.
