Motor Protection System Delivers Advanced Graphical Diagnostics

June 27, 2007

GE Multilin introduced the enhanced 369 Motor Protection System. Designed for medium-voltage motors, the 369 delivers a simple setup configuration, an improved front panel, advanced graphical diagnostics, comprehensive communications and complete traceability of all setting changes.

The need to manually program individual protection settings was eliminated with the six-step motor settings auto-configurator. By utilizing motor nameplate data, current and voltage sensing  parameters, motor starting and application information, the feature automatically generates a complete settings file.

A front-panel design, including LED indicators for conditions such as, "stopped:, "started", "running", "overload" and "trip" provide quick, visual indication of motor status.

The 369 Motor Heath Report's graphs and tables, easily allows the operator to "see" how their motor is operating with motor start/stop history, trip details, learned acceleration time and starting current. Plant operators now have an unprecedented insight into the status of their motors, minimizing unplanned shutdowns and planned downtime duration. In addition, the Event Recorder, which has doubled its capacity, captures graphical event-triggered oscillography records and the all-new Motor Start Data Logger offers users unparalleled  access to motor start/stop waveforms.

Security has become a critical issue at many industrial facilities. GE Multilin's patented Security/Change History Report offers complete traceability of all setting changes. These detailed reports show the history of all relay configuration changes including the modified settings, who made the change and when the change was made.

Coupled with flexible, open communication protocols, supporting Modbus (Serial & Ethernet), DeviceNet, and Profibus, the 369 can integrate with new or existing monitoring and control systems and connected loads.

The 369 utilizes one of the industry's most advanced motor thermal models, which includes 15 standard overload curves that can be customized using FlexCurvesT.
