3-phase variable transformers, more commonly called 3-phase variacs, are essential for measuring transformer health and can perform AC and DC motor tests. ATEC carries a variety of variacs (1-phase, 3-phase, and 6-phase) from manufacturers such as
Staco.
What Does a 3-Phase Variac do?
Variacs test ratio, winding resistance, tap changer, excitation current, short circuit impedance, and more. When the user is continuously monitoring performance of a transformer or motor, they can address any necessary maintenance immediately, saving time and money down the line. Verify proper voltage output of your 3-phase transformer and motor with a variac to prevent corrosion and breakdowns.
