Product Description
The Eltel ATRM-200 Automatic Transformer Ratiometer measures the transformation ratio of transformers in a ratiometric circuit. As the measurement is conducted at low flux density, this measurement is equivalent to the turns ratio of the transformer. Besides measuring turns ratio, ATRM-200 also measures phase angle deviation between the tested windings. As a perfect transformer should show no phase difference between the input and output, the measured phase angle deviation is an indicator of possible shorted turns or poor core quality.
