Functional Features

• Real-Time Gas Detection: Monitors dissolved gases in transformer oil with high precision, providing early warnings of internal faults such as partial discharge, arcing, or insulation degradation.
• Alarm Management: Supports configurable thresholds for gas concentration and rate-of-change alarms, with three relay outputs for local or remote signaling.
• Analog Output: 4-20 mA signal for integration with SCADA, DCS, or data loggers, enabling trend analysis and remote monitoring.
• User Interface: Backlit LCD displays real-time gas readings, alarm status, and system diagnostics. Local buttons allow for alarm acknowledgment and basic configuration.
• Network Communication: RS-485 port supports daisy-chain connections for up to 32 controllers or 201Ti units, forming a local network with a maximum range of 1200 meters (4000 feet).
• Self-Diagnostics: Performs automatic system checks and logs events for maintenance troubleshooting.
• Rugged Design: NEMA 4X/IP66-rated enclosure ensures reliable operation in harsh environments, including extreme temperatures and high humidity.

Application Scenarios

• Power Generation: Online monitoring of transformers in power plants to detect incipient faults and prevent catastrophic failures.
• Substations: Continuous protection of distribution transformers in electrical grids.
• Petrochemicals: Monitoring transformers in refineries and chemical plants where equipment reliability is critical.
• Renewable Energy: Protecting transformers in wind and solar farms to minimize downtime.
• Industrial Manufacturing: Ensuring safe operation of transformers in steel mills, automotive plants, and other heavy industries.

Design Advantages

• Early Fault Warning: Enables proactive maintenance by identifying gas trends before they reach critical levels.
• Cost-Effective: Reduces the need for manual oil sampling and laboratory analysis, lowering operational costs.
• Scalability: Supports expansion of monitoring networks by adding more controllers or sensors.
• Ease of Integration: Compatible with standard industrial communication protocols (Modbus, RS-485) for seamless system integration.
• Reliability: Built with industrial-grade components to withstand harsh conditions and ensure long-term stability.
