Product Details

The Vanguard ATRT-03 Automatic Three Phase TTR is a three-phase, transformer turns-ratio tester. It is lightweight, rugged, portable, and is designed for transformer testing at utility power substations.

 

The Vanguard ATRT-03/03A determines the transformer turns ratio by accurately measuring the voltages across the unloaded transformer windings and then displaying the ratio of these voltages (ratios range from 0.8 to 15,000), and calibrates each measurement to ensure the turns-ratio accuracy.
