4.Compare with TTR771

Applications

TTR773 is one very typical transformer turns ratio test set, widely used for Grid, substation and power plant.

TTR 771 is designed for high-end customers which date upload & analysis functions is required. TTR771 is usually positioned at electrical test vehicles, and controlled by one compute with other test instrument. It is also one part of transformer test table together with transformer resistance tester, transformer tap change test set. and so on.
