H201Ci-1 GE HYDRAN One Channel Controller

The H201Ci-1 GE HYDRAN One Channel Controller is a specialized device designed for monitoring and protecting electrical transformers, particularly focusing on detecting dissolved gases and moisture in transformer oil—key indicators of incipient faults like partial discharges, overheating, or arcing. Below is a detailed breakdown of its features and specifications:

Key Features

1. Single-Channel Monitoring
   • Designed for applications where monitoring one parameter (e.g., hydrogen gas concentration) is sufficient.
   • Suitable for smaller transformers or cost-sensitive installations.
2. Voltage Input Range
   • 90-132 VAC / 180-264 VAC: Dual-range input supports both standard North American (120 VAC) and European/international (230 VAC) power systems.
   • Auto-sensing or manual selection (depending on model) ensures compatibility with local voltage requirements.
3. GE HYDRAN Technology
   • Utilizes a proven sensor to detect hydrogen (H₂) gas, a primary byproduct of transformer faults.
   • May also integrate moisture (water content) monitoring, depending on configuration.
4. Alarm and Control Functions
   • Provides adjustable alarm thresholds for gas concentration or moisture levels.
   • Outputs (e.g., relays, 4-20 mA signals) for integration with SCADA systems or triggering protective actions.
5. Compact and Rugged Design
   • Built for harsh industrial environments (NEMA/IP ratings may apply).
   • DIN-rail or panel-mount options for flexible installation.

Technical Specifications

• Power Supply:
  • 90-132 VAC (50/60 Hz) or 180-264 VAC (50/60 Hz).
  • Power consumption: Typically < 50 VA.
• Sensor Type:
  • Fuel cell or polymer-based sensor for H₂ detection (long-life, low maintenance).
  • Optional capacitance or dielectric sensors for moisture measurement.
• Output Signals:
  • Relay contacts (NO/NC) for alarms.
  • Analog output (4-20 mA) for remote monitoring.
  • RS-485/Modbus communication (optional in some models).
• Operating Environment:
  • Temperature: -20°C to +60°C (-4°F to +140°F).
  • Humidity: 0-95% non-condensing.
• Certifications:
  • Compliance with IEC 61850, IEEE C57.12.90, or other relevant standards (check GE documentation).

Applications

• Power Transformers: On-load tap changers (OLTCs), distribution transformers.
• Industrial Equipment: Motors, generators, reactors where gas/moisture monitoring is critical.
• Utility Substations: For early fault detection to prevent catastrophic failures.

Advantages

• Early Warning: Detects faults before they escalate, reducing downtime and repair costs.
• Ease of Use: Simple setup with user-configurable alarms and calibration.
• Reliability: GE’s HYDRAN technology is industry-proven with decades of field use.

Considerations

• Single-Channel Limitation: For multi-parameter monitoring (e.g., H₂, CO, moisture), consider GE’s multi-channel controllers (e.g., H201X).
• Sensor Lifespan: Fuel cell sensors typically last 5-10 years but require periodic calibration.

Support and Documentation

• Refer to GE’s official manuals for wiring diagrams, calibration procedures, and troubleshooting.
• Contact GE Grid Solutions or authorized distributors for spare parts or technical assistance.
