Product Technical Overview

The GTTS Series gas-insulated metal-clad test transformer integrates the step-up transformer, voltage divider, and coupling capacitor within a grounded coaxial steel enclosure filled with SF6 gas. Directly docked to the tested GIS equipment via disconnect switches or SF6-air testing bushings, completely eliminating airborne corona and external interference.
