TR 100

 

The TR 100 offers a wide turns ratio measurement range from 0.8 to 30,000 to 1, with selectable test voltages of 4, 40 and 100 V, making it an ideal instrument for quick and easy testing of single or three-phase transformers. The selectable test voltages enable the instrument to measure turns ratios with high accuracy in an electrically noisy environment.

The TR 100 measures turns ratios per the IEEE C57.12.90 standard testing method. It is suitable for testing power transformers, current transformers (CT’s), potential transformers (PT’s), and voltage regulators. It can measures turns ratio, phase angle, excitation current and polarity.
