New Product: Wrindu Transformer Turns Ratio Tester (RDB-II)

Wrindu TTR Tester

We are excited to introduce our latest addition to the Wrindu product lineup – the RDB-II Transformer Turns Ratio Tester. Developed with cutting-edge technology and precision engineering, this tester is designed to overcome the limitations of traditional ratio bridge testing methods. Whether you are in the manufacturing, installation, or maintenance phase of power transformers, this high-performance device ensures accurate and efficient testing, making it an essential tool for your electrical testing needs.

Why Choose the RDB-II Transformer Turns Ratio Tester?

The RDB-II Transformer Turns Ratio Tester is a powerful instrument that simplifies the testing process, offering intuitive operation and accurate results. It is ideal for use in a variety of settings, including semi-finished and finished power transformer production, installation checks, and preventive maintenance of operating transformers. This tester guarantees that your transformers’ voltage ratios and tap changers are functioning as expected, ensuring reliable operation and preventing costly failures.

Key Features of the RDB-II Transformer Turns Ratio Tester:

  1. High Precision with Inverter Technology:

    • The RDB-II employs a three-phase precision inverter, which eliminates harmonic interference from the mains power supply, ensuring more accurate measurements.

    • Even when using a generator as the power source, there is no loss of measurement accuracy.

  2. Fast Testing with Three-Phase Output:

    • The tester’s three-phase output significantly improves testing speed.

    • It can measure the phase angle between each phase, automatically identifying the transformer’s connection group (0 to 11).

  3. Versatile Compatibility:

    • The RDB-II can measure a wide range of transformers, including Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, and balance transformers.

    • It offers the most comprehensive range of measurement parameters, catering to various industrial needs.

  4. Robust Protection Features:

    • Includes protection against high and low voltage reverse connections, turn-to-turn short circuits, and tap changer misalignment.

    • The instrument is designed with output short-circuit protection for enhanced stability.

  5. Automated Measurements:

    • After inputting the rated transformer parameters, the tester automatically measures the transformer’s ratio, error value, and tap changer position.

    • Specially designed to handle asymmetric tap connections, it can accurately measure up to 99 tap changer positions.

  6. User-Friendly Interface:

    • The 7-inch high-definition color touch-screen LCD simplifies the operation, guiding users through each step with on-screen prompts.

    • The modular display makes it easy to read and interpret results quickly.

  7. Paperless Reporting:

    • Equipped with printout, USB, and RS232 interfaces, the RDB-II enables paperless office functionality.

    • Effortlessly download and store test results, reducing manual paperwork and streamlining your reporting process.

  8. Rugged and Durable Design:

    • Built with a multi-functional engineering plastic box, the tester is cold-resistant, waterproof, shock-resistant, and anti-falling, making it perfect for field testing under harsh conditions.

  9. Wireless Control & Data Upload:

    • A dedicated app is available for remote control of the instrument and the ability to store and upload test data for future reference.
