GE Multilin M60 Motor Protection System

Description

The M60 motor protection system offers comprehensive solutions for medium to large three-phase motors, providing advanced protection, control, and diagnostics. It includes features such as thermal modeling with RTD and current unbalance biasing, stator differential protection, reverse and low forward power detection, external RRTD module support, handling of two-speed motors, reduced voltage starting, broken rotor bar detection, and more.

Key Benefits

• Improved protection sensitivity with a flexible thermal model including standard, custom, and voltage-dependent overload curves.
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, settings via SCL files, and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensuring interoperability, device management optimization, and reduced ownership costs.
• Routable GOOSE (R-GOOSE) for wide area protection and control applications.
• Simplified programming with the EnerVista™ M60 motor settings autoconfigurator.
• Robust network security supporting Critical Infrastructure Protection through user command logging and dual permission access control.
• Application flexibility with multiple I/O options including high-density I/O, programmable logic, modularity, and specific customization.
• High-end fault and disturbance recording capabilities.
• Reduced relay-to-relay wiring costs through high-speed inter-relay communications.
• Enhanced motor-learned data for critical preventative maintenance information.
• Supports the latest edition of waveform capture (COMTRADE 2013) for simplified fault records management.
• Integrated large, full-color display for real-time visualization, bay mimic control, annunciator functionality, and graphical phasor visualization.

Applications

• Protection and control of medium to large three-phase induction motors across popular construction types.
• Automation or process control functionality.
• Protection of medium to large synchronous motors when used with the SPM.
• Stand-alone protection or integration into automated substation control systems.
