GE H201TI

I. Overview

The GE H201TI is a key device in General Electric (GE)'s Hydran series, specifically designed for online monitoring of dissolved gases in transformer oil (DGA). It is used to provide real-time early warning of transformer faults, thereby reducing the risk of unplanned power outages. Its core function is to offer early fault warnings by continuously monitoring the concentrations of gases such as hydrogen, carbon monoxide, acetylene, and ethylene. In addition, some models are also applicable to fields like industrial automation, power adapters, and motor control.
