Universal Single/Three Phase TTR Tester Rugged Portable Turns Ratio Meter for Transformer Testing
General Information:
The Transformer Turns Ratio (TTR) Tester is a high-accuracy, portable instrument designed to measure the turns ratio, excitation current, phase angle deviation, and polarity of power transformers. It ensures transformer windings are correctly configured and free from inter-turn faults, short circuits, or incorrect connections.
Features:
High Accuracy: Measures turns ratio with accuracy up to ±0.05%, meeting IEC 60076 and IEEE C57.12.90 standards.
Auto Range & Auto Polarity Detection: Automatically identifies vector group, polarity (additive/subtractive), and connection type (Y, Δ, Z, etc.).
Multi-Voltage Output: Built-in programmable test voltage (e.g., 8 V, 40 V, 100 V AC) suitable for various transformer types—from small distribution units to large power transformers.
Color LCD Display with Real-Time Timer: Clear graphical interface shows live test results, wiring diagrams, and a visible countdown/sweep timer bar during measurement for user guidance.
Vector Group Verification: Supports all standard vector groups (e.g., Dyn11, YNd1, Yy0) with automatic comparison against expected values.
Data Storage & Export: Stores up to 1,000 test records internally; supports USB/Bluetooth export to PC for report generation.
Safety Protection: Overvoltage, overcurrent, and open-circuit protection ensure operator and equipment safety.
Battery & AC Dual Power: Rechargeable lithium battery enables field operation for >8 hours; also operable via AC adapter.
Lightweight & Rugged Design: Compact and portable (<5 kg) with shock-resistant casing for on-site use.
