Product Description
Factory-Direct Price All-in-One Portable TTR Tester for Single/Three-Phase Transformers Turns Ratio Test Set

General Information:

The TTR-1000 Transformer Turns Ratio (TTR) Tester is a state-of-the-art, microprocessor-based instrument designed for fast, accurate, and reliable measurement of turns ratio, excitation current, and winding connections of single-phase and three-phase power transformers, potential transformers (PTs), and current transformers (CTs). With its advanced digital signal processing and user-friendly interface, the TTR-1000 is an indispensable tool for transformer manufacturing, commissioning, routine maintenance, and diagnostic testing, ensuring the health and efficiency of your power systems.

Features:

  • High Precision & Wide Range:​ Delivers exceptional accuracy for turns ratio measurements across an extensive range (e.g., 0.8 to 15000), suitable for virtually all distribution and power transformers.

  • Fully Automatic Testing:​ Simply connect the leads and press "Test." The instrument automatically determines the phase, applies the correct test voltage, calculates the ratio, and displays results clearly—minimizing operator error.

  • Three-Phase & Single-Phase Testing:​ Capable of measuring single-phase transformers and automatically testing three-phase transformers in various vector groups (Yy, Dd, Yd, Dy, etc.) with sequential results.

  • Winding Connection Diagnostics:​ Automatically identifies wiring errors and common transformer faults such as shorted turns, open windings, and incorrect tap changer positions.

  • Excitation Current Measurement:​ Measures magnetizing (excitation) current, a key parameter for detecting core and winding issues like inter-turn shorts or core insulation problems.

  • Phase Angle Measurement:​ Calculates and displays the phase displacement between voltages, crucial for verifying transformer vector group.

  • Large Color Display & Intuitive UI:​ Features a clear LCD/TOUCH screen that shows comprehensive results, connection diagrams, and pass/fail indications based on pre-set limits.

  • Built-in Memory & Data Management:​ Stores thousands of test results with date/time stamps. Data can be reviewed on the device or transferred to a PC via USB or Bluetooth for report generation and trend analysis.

  • Robust & Portable Design:​ Housed in a rugged, field-ready case with protective test leads. Lightweight and battery-operated for extended use in substations and remote field locations.

  • Safety & Reliability:​ Equipped with built-in protections against over-voltage, over-current, and reverse polarity. Auto-discharge circuitry ensures operator safety after testing.
