  • The unique design of the TTR100-1 allows the user to operate the test set while holding it in one hand. Realizing the extreme environments in which the TTR100-1 must operate, special attention has been paid to making it extra rugged, with a high impact, shock resistant case, yet incredibly lightweight at 3.3 lb. (1.5 kg). It weights less than any other commercially available instrument on the market.

    Its rugged and robust design makes this instrument well suited for use in a variety of harsh environments. The TTR100-1 is particularly suited for testing in substations and transformer-manufacturing environments where testing single and three-phase transformers can be performed. The TTR100-1 provides reliable results, helping the user in determining the condition of the transformer under test. It features a high contrast LCD screen which can be seen in bright or ambient light.

    The TTR100-1 and its lead set utilizes a METAL connection on both the instrument end and lead. This enhanced feature makes the instrument much more robust, improving reliability even under the harshest conditions.

    This unit measures the highest turns ratio in the industry with an accuracy of 0.2% or better and with the lowest excitation voltage. Another excellent feature of this TTR us the ability to accurately measure phase deviation of the transformer primary versus secondary. This measurement is also useful in verifying phase errors in PTs and CTs.

    Features

    • Single and three-phase transformer testing (up to 1 MVA)
    • Lightweight, handheld
