HZTTR80A Three Phase Transformer Turns Ratio Tester
HZTTR80A Transformer Turns Ratio Tester
The HZTTR80A Transformer Turns Ratio Tester is a fully automatic, multi-function instrument designed for comprehensive transformer diagnostics. It integrates turn ratio measurement, voltage ratio calculation, vector relationship analysis, winding connection identification, polarity detection, tap position determination, and excitation current measurement into one portable, field-ready device. Supporting both single-phase and three-phase transformers - including autotransformers, Z-type transformers, and phase-shifting transformers - the HZTTR80A delivers high-precision results across a 0.9 to 10,000 ratio range with selectable 5V or 80V test output.
Equipped with a 7-inch HD color touchscreen, Android APP remote control, and blind-test capability that can identify unknown winding configurations, the HZTTR80A eliminates guesswork in the field and dramatically reduces testing time. Built to withstand harsh environments, both the main unit and its cable box are housed in a rugged engineering plastic case that is cold-resistant, heat-resistant, sealed, waterproof, and shockproof.
Product Value
Speed + Precision: Simultaneous three-phase measurement reduces field testing time by up to 60% compared to single-phase instruments, while delivering accuracy as high as ±0.1% on low-ratio ranges.
Blind-Test Intelligence: Even with completely unknown winding connections, the instrument automatically determines vector relationships, connection groups, and ratio values - eliminating manual reference lookups and wiring errors.
Complete Transformer Health Picture: Beyond ratio testing, excitation current measurement helps detect shorted turns, core issues, and tap-changer defects that ratio tests alone may miss.
Seamless Data Management: 200-group onboard storage, USB export, thermal printing, and Android APP connectivity ensure every test result is instantly documented and reviewable.
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.
