GE H20CI-1 HYDRAN SingleChannel Transformer Monitoring Controller

The GE H20CI-1 is an intelligent monitoring controller used in the HYDRAN 201i transformer diagnostic system. The device continuously receives data from a connected HYDRAN 201Ti sensor and processes dissolved gas measurements to provide early warning of developing transformer faults.

By monitoring combustible gases dissolved in transformer oil, the controller helps maintenance teams identify insulation degradation, overheating conditions, partial discharges, and other fault mechanisms before they result in costly equipment failures. The system supports local display, remote communication, alarm management, and integration with SCADA or asset management systems.

The H20CI-1 includes configurable alarm thresholds, analog output transmission, and communication interfaces that allow operators to track transformer condition from centralized monitoring centers. Its weather-resistant enclosure supports installation in demanding outdoor utility environments. 

Continuous Transformer Health Monitoring

Provides around-the-clock dissolved gas analysis to support predictive maintenance programs and improve transformer reliability.

Advanced Alarm Management

Supports multiple alarm levels, including gas concentration alarms and system fault notifications, helping operators respond quickly to abnormal conditions.

Integrated Communication Interfaces

RS-232 and RS-485 ports allow seamless integration with SCADA, DCS, and utility monitoring networks.

Rugged Outdoor Design

The NEMA 4X enclosure provides protection against moisture, dust, and harsh environmental conditions encountered in substations and industrial sites.

Analog Output Capability

Configurable analog outputs simplify connection to supervisory control and data acquisition systems. 

Use ESD protection when handling the GE H20CI-1.

Ensure correct wiring and secure connections.

Avoid installation near strong electromagnetic interference sources.
