Portable TTR Tester with 0.1% Accuracy & LCD Display Screen – GAOTek

Description

Overview

GAOTek Portable TTR Tester with 0.1% Accuracy & LCD Display Screen equipment is particularly suitable for Z-Z-winding transformers, rectifier transformers, and electrical systems railway Scott and inverse Scott balanced transformers. Input single-phase power and generate three or two phases of power by the internal power module, output to the high voltage side, and then sample high voltage and low voltage at the same time. Finally, the group, variation ratio, error, and phase difference are calculated. Equipped with a large-screen LCD, a friendly man-machine interface, is fully functional, and easy to operate. It can be directly controlled by the upper computer through a USB port, completing settings, measuring, uploading, saving, and printing data, etc.  

Features
