Transformer Turns Ratio Tester

The ART-3D^TM series of ratio meters are high-precision instruments, designed to measure turn ratios, phase displacements, excitation currents of single phase and three phase power, distribution, and instrument transformers in conformity with IEEE C57.12.90 & IEC 60076 standards.

The ART-3D^TM is top-of-the-line turns ratio tester, well-thought, and high precision manufactured instrument.
