  • RS232 for data transfer and printing
  • Stores 200 test results and 100 user-defined transformer test settings

The Megger TTR100-1 is an automatic handheld, battery operated transformer turns ratio test set used to measure the turns ratio, excitation current, phase displacement, dc resistance and polarity of windings in single- and threephase distribution transformers (tested phase by phase), potential & current transformers, and tapped transformers.Deviations in the mentioned measurements will quickly indicate problems in transformer windings or in the magnetic core circuits.

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.
