GE H201Ci-1

The GE H201Ci-1 is a single-channel controller from GE's Hydran series, specifically designed for precise control and monitoring in industrial applications. It is particularly suitable for detecting dissolved gases in transformer oil (DGA) and providing fault early warning. When used in conjunction with the H201Ti intelligent transmitter, it enables real-time monitoring of transformer health status, finding wide application in power systems such as power plants, substations, petrochemicals, and metallurgy.

Product Features

High Precision and Reliability

• Utilizes high-quality electronic components and advanced craftsmanship to ensure ±1% measurement accuracy and long-term stability.
• Supports overload protection (150% overload capacity for 1 minute) and short-circuit protection.

Modular Design

• Enables quick installation, configuration, and maintenance, with support for flexible expansion.
• Allows configuration of output signal types (such as 0-1 mA, 0-1V) via jumpers.

Functional Integration

• Equipped with a digital LCD display (0-1999 ppm range) and illuminated buttons indicating alarm status.
• Supports remote monitoring, SCADA system integration, and multi-device networking (maximum 32 controllers and 128 H201Ti units).

Safety and Environmental Adaptability

• Compatible with various industrial environments (high temperature, high humidity, vibration) and features dustproof and waterproof design.
• Built-in heater for stable operation within the range of -40°C to +55°C.

Structure and Composition

Core Components

• Digital display circuit board: LED displays dissolved gas concentration (ppm) with alarm indicators.
• Electronic circuit board: Integrates functions such as TDM pulse decoder, alarm relay driver, and analog output amplifier.
• Connection terminals: Main terminals for AC power, alarm contacts, and analog output.

Installation and Wiring

• Cable conduits: All cables must be introduced through steel conduits (or armored cables), with flexible conduits used near the equipment for easy maintenance.
• Supervisory chain cable: Connects H201Ti and H201Ci-1 to transmit TDM pulse signals (gas concentration, alarm status).
• Grounding requirements: Cable shielding layers and conduits must be grounded at one point to avoid interference.

Application Fields

Power Systems

• Transformer health monitoring (such as analysis of gases like hydrogen, methane, ethylene) to early warn of faults such as overheating and partial discharge.
• Integration with SCADA systems to achieve proactive maintenance.

Industrial Automation

• Process variable control in industries such as chemical, pharmaceutical, and food processing.
• Data collection and monitoring in energy management systems.

Other Scenarios

• Convenient operation of hard-to-reach transformers (such as those installed at high positions).
• Application in power modules of industrial equipment (providing stable power supply).

Installation and Maintenance

Installation Steps

• Cable laying: Use steel conduits or armored cables, ensuring the total length of the supervisory chain cable does not exceed 1200 meters.
• Wiring specifications:
  • The six wires of the supervisory chain cable must be marked and correctly connected to the main terminals.
  • Analog output cables must be grounded at one end to avoid interference.
• Grounding and protection: Conduits and cable shielding layers must be grounded at one point to prevent electromagnetic interference.

Maintenance Recommendations

• Regular inspection: Verify that the displayed values (e.g., 1999 ppm) and analog output (20 mA) meet expectations.
• Troubleshooting: Perform remote diagnosis via RS-232/USB interfaces and check the status of alarm relays.
• Environmental monitoring: Ensure the operating temperature is within the range of -20°C to 70°C to avoid the impact of extreme conditions.
