GE H201TI transformer monitoring

GE H201Ti is an online transformer monitoring device (DGA monitor) from General Electric (GE). It is primarily used for real-time detection of dissolved gases in transformer oil and for early fault warning.

1. Core Functions and Applications

Early Fault Warning:
By monitoring changes in the concentration of gases dissolved in oil (such as hydrogen, methane, acetylene, etc.), the device can identify potential faults at an early stage and prevent fault escalation.

Real-Time Data Monitoring:
Supports continuous monitoring and provides a composite value of fault gases (a single ppm reading). It also features full system self-checking and self-diagnostic functions.

Application Scenarios:
Widely used in power transformers, oil refineries, natural gas plants, chemical plants, and other industries with extremely high safety requirements.

2. Technical Specifications and Features

Sensor Technology:
Uses a Hydran fuel cell gas sensor with high detection sensitivity (100% response to hydrogen).

Communication Interfaces:
Supports Modbus RTU / RS485 protocol and can be integrated with SCADA systems for remote data transmission and centralized monitoring.

Environmental Adaptability:
Wide operating temperature range (−20 °C to +50 °C, with some models supporting −40 °C to +85 °C) and a high IP protection rating, making it suitable for harsh environments.
