The Vanguard Instruments ATRT-03A Series 2 is a third-generation, microprocessor-based, automatic, three-phase, transformer turns-ratio tester. It is a lightweight, rugged, portable unit that is designed for transformer testing at utility power substations.
The ATRT-03A Series 2 determines the transformer turns ratio using the IEEE C57.12.90 measurement method. It outputs an excitation test voltage to the transformer primary windings. The induced secondary voltage is sensed and the transformer turns ratio is calculated.
