GE Hydran H201Ti CE-H2 Dissolved Gas Monitor

Product Brief Description

The GE Hydran H201Ti CE-H2 is an online dissolved gas-in-oil (DGA) transmitter for power transformers. It adopts fuel cell sensing technology to continuously detect key fault gases in transformer oil, delivering real-time gas concentration data for early transformer fault prediction and asset protection.

Product Features

• Detects hydrogen, carbon monoxide, acetylene and ethylene for transformer thermal & arcing fault warning
• Built-in local LCD display for on-site gas value viewing and parameter setup
• Isolated 4-20mA analog output and Modbus RS-485 digital communication
• Multiple relay alarm outputs for high gas concentration and device fault alerts
• Automatic periodic self-diagnosis function to reduce blind monitoring risks
• Direct valve mounting design, no external sampling pump or complex pipeline needed
• NEMA 4X / IP66 rugged enclosure suitable for outdoor substation environments

Application Scenarios

• Power transmission and distribution oil-immersed power transformers
• Substation, power plant and renewable energy station transformer condition monitoring
• Electrical utility predictive maintenance and transformer asset management
• Integration with SCADA, DCS and remote online monitoring systems
• Industrial large oil-filled reactors and shunt reactor fault early warning

FAQ

Q1: What gases can H201Ti CE-H2 measure?

A1: It mainly monitors hydrogen, carbon monoxide, acetylene and ethylene, the key fault characteristic gases of transformers.

Q2: Can it connect to SCADA system?

A2: Yes, it supports 4-20mA analog signal and Modbus RTU over RS-485 for SCADA integration.

Q3: Does it require an external oil sampling pump?

A3: No, it adopts passive oil sampling and can be directly installed on the transformer drain valve.

Q4: What is the alarm function?

A4: It provides configurable high / high-high gas alarms and sensor fault alarms via dry relay contacts.

Q5: Is this unit suitable for outdoor installation?

A5: Yes, IP66 / NEMA 4X enclosure supports outdoor substation installation with weather protection.
