3 Phase Transformer Turns Ratio Test Set is designed to measure the Turns ratio of power, instrument, and Distribution Transformers in a Substation or manufacturing & Maintenance Environment. The turns ratio test is an AC low voltage test which determines the ratio of the Primary winding to all other Secondary windings at no-load. The Turns Ratio Test is performed on all taps of every winding.3 Phase TTR Highest Turns Ratio accuracy With ratio up to 200:1. TTR Tester is a lightweight and easy operated.
