GE H201Ti

The GE H201Ti is a gas analysis monitor primarily designed for dissolved gas analysis (DGA) in transformer oil, which helps to monitor and predict transformer failures. This device is part of GE’s Hydran product line and is widely used in power systems like power plants, substations, and industrial enterprises across industries such as petrochemical, metallurgy, and transportation (e.g., railways and subways).

Key Features:

  1. Dissolved Gas Analysis: The H201Ti continuously monitors key gases like hydrogen (H₂), carbon monoxide, acetylene, and ethylene, which are indicators of potential transformer faults. The monitor offers real-time readings and stores historical data for analysis.
  2. Compact Design: It is small, easy to install, and doesn’t require additional piping or calibration. Installation can be done on a single valve for dynamic oil sampling without extra pumps.
  3. Communication: Supports multiple communication protocols like Modbus®, enabling integration with existing monitoring systems. It also features a USB port for easy data access, and compatibility with GE’s Perception™ Fleet software for trend and data analysis.
  4. Alarming: Multiple alarm thresholds can be set, providing early warning of transformer issues to avoid unplanned outages.

Applications:

  • Power Systems: Used in transformers and other electrical equipment to ensure smooth operations and minimize the risk of unexpected failures.
  • Industrial Applications: Can be deployed in sectors like petrochemical, metallurgy, and mining to monitor critical equipment.

In addition to the DGA system, the GE H201Ti model is also used in single-phase motors and Hall effect sensors for various industrial applications like power measurement and motor control.

For more technical details, the H201Ti can measure within a range of ±20 A to ±1000 A, with an accuracy of 0.5% and a response time of less than 1 μs. It’s powered by a 12-24 V DC source and operates between -40°C to 85°C, making it suitable for harsh environments​
