GE Multilin T35 Transformer Protection System

The GE Multilin T35 Transformer Protection System is a microprocessor-based protection and control system designed to safeguard medium and large transformers. It offers a range of protective functions, including overcurrent protection, differential protection, and temperature monitoring, making it ideal for use in electrical utilities, industrial plants, and commercial facilities.

Key Features

• Differential Protection: Provides protection against phase-to-phase and phase-to-ground faults within transformer windings.
• Overcurrent Protection: Includes both time-overcurrent and instantaneous overcurrent protection.
• Temperature Monitoring: Prevents transformer overheating by continuously monitoring temperature.
• Ground Fault Protection: Detects ground faults to minimize damage to the transformer.
• Fault Recording: Stores detailed fault logs and provides real-time diagnostic data for troubleshooting.
• Communication Protocols: Supports Modbus RTU, DNP3, and IEC 61850 for seamless integration with automation systems.
• User Interface: Features a high-resolution LCD display and keypad for local control and configuration.
• Event Logging: Provides time-stamped event logs for fault analysis.
