Description
The Megger TTR310 measures transformer turns ratio, excitation current and phase deviation for commissioning and maintenance checks.
An integrated text-based display and keypad support standalone setup, stored results and comparison with nameplate ratios. Automatic phase selection reduces reconnection work on three-phase transformers. RS-232 transfer supports external reporting; an external printer is optional. This page covers the original TTR310 model.
