Huazheng High Accuracy Field Testing Battery Powered 3 Phase TTR Measuring Instrument
I.Main Functional Features
I. Overview
1.1 Product Overview
The HZTTR80AP transformer ratio test device is a fully automatic tester. It integrates the testing functions of turn ratio, voltage ratio, vector relationship, winding connection, polarity, tap position, and excitation current. This tester is a lightweight and portable instrument, with both the tester and its accessories housed in a multi-functional engineering plastic case that is resistant to cold, heat, sealing, waterproof, and shockproof, 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 throughout using a dedicated APP downloaded on an Android phone or tablet, allowing for the storage and upload of test data for easy review.
1.2 Main Functional Features
▪ Capable of PT ratio and polarity testing.
▪ With a blind-testing function, it can accurately measure the turns ratio of a three-phase transformer even when its connection group type is unknown. It can also correctly determine the phase relationship between the primary and secondary sides and accurately calculate the group number.
▪ Capable of testing autotransformers, Z-type transformers, and phase-shifting transformers.
▪ Added tap mode settings to accommodate transformers with high voltage at high tap positions and low voltage at high tap positions.
▪ Added low-voltage side tap settings to accommodate transformers with taps on the low-voltage side.
▪ Graphical display settings for more intuitive readings.
▪ Simultaneous measurement of three-phase ratios during three-phase transformer testing for faster testing speed.
▪ It is powered by a high-capacity lithium battery, enabling not less than 1,000 measurements to be conducted on a single charge.
▪ It features an automatic shutdown function. If the instrument is not operated within 30 minutes, it will emit an alarm and then turn off the power.
1. Grounding Terminal: Before conducting any tests, please safely ground the grounding terminal to avoid the risk of electric shock.
2. Charging dock and switch: The charging dock serves as the charging input port for the battery, while the switch is used to turn the tester's power on or off.
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.
