Technical Data

The GE Multilin 745-W2-P5-G5-HI-A-L-R-E-H is a Transformer Protection System designed to manage and safeguard transformers of any size.

Primary and Back-Up Protection: The 745 provides primary protection and back-up protection for small, medium, and large power transformers. It can be applied to both two-winding and three-winding transformers.

Multiple Inputs: The relay uses multiple current and voltage inputs to monitor and protect transformers. These inputs allow it to perform functions such as differential protection, ground differential phase protection, neutral protection, ground overcurrent protection, over-fluxing protection, and on-load tap changer protection.

FlexLogic Automation: The 745 incorporates FlexLogic automation capabilities, allowing you to create custom equations and logic for specific protection scenarios. This flexibility reduces the need for auxiliary components and wiring.

Built-In Metering: Accurate metering functions are built into the relay, providing essential data for monitoring transformer performance.

Communication Protocols: The relay supports Modbus and DNP 3.0 Level 2 protocols through embedded Ethernet, standard RS232, RS485, and RS422 serial ports.

Security Features: The 745 includes an Audit Trail for traceability of system configuration changes and optional conformal coating for harsh environments.

Draw-Out Capability: Its draw-out case minimizes downtime during maintenance.
