Multilin 859

Advanced Motor Monitoring & Diagnostics

The Multilin 859 offers an integrated, cost-effective monitoring and diagnostics features that leverage existing relay data without the need for additional devices, sensors, wiring and training. The 859 utilizes both Electrical Signature (ESA) and Motor Current Signature Analysis (MCSA) to provide the early detection and warning of a wide range of electrical, thermal and/or mechanical abnormalities that may affect a motor’s performance or operational life.

Motor failures and faults can have a significant impact on a process, resulting in loss of revenue and material. Predictive maintenance and situational awareness to the motors operating condition is critical to helping reduce unplanned downtime and energy consumption - maximizing motor life.

Motor monitoring & diagnostic features include stator turn-to-turn fault, broken-rotor-bar detection, roller-bearing faults, foundation looseness, eccentricity, and misalignments.

Electrical Abnormalities If undetected, insulation failure can evolve into phase or ground faults, causing equipment damage or loss, and significant unplanned downtime. The 859’s advanced motor monitoring and trending capabilities provide identification of critical electrical conditions including: Stator inter-turn insulation failure Phase-phase insulation failure Stator ground failure Loss of load/process   Unbalance current Power factor Under/Over frequency   Thermal Abnormalities The 859 continuously and proactively monitors the motor for Thermal Capacity Used (TCU) to provide early warning of thermal stresses including: Extreme starting conditions Ambient temperature Forced cooling stops Harmonics   Single phasing Unbalance current Increase load Locked rotor   Mechanical Abnormalities Without the need for additional sensors or probes, the 859 utilizes GE's patented Electrical Signature Analysis (ESA) / Motor Current Signature Analysis (MCSA) to identify mechanical abnormalities in the motor including: Broken rotor bar Bearing failure Mechanical jam   Static & dynamic eccentricity Foundation looseness Misalignments

Communications & Cyber Security

The 859 provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provide s high-bandwidth communications, allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The 859 also supports two independent IP addresses, providing high flexibility for the most challenging of communication networks.

Software & Configuration

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the Multilin 859.

EnerVista provides all the tools to monitor the status of the protected asset, maintain the device and integrate the information measured by the Multilin 8 Series, into SCADA or DCS process control systems. The ability to easily view sequence of events is an integral part of the setup software, as postmortem event analysis is critical to proper system management.

EnerVista Launchpad

The setup tools within Launchpad allow for the configuration of devices in real-time, by communicating via serial, Ethernet or modem connections, or offline by creating device setting files to be sent to devices at a later time.

8 Series Setup Software

8 Series Setup Software is single setup and configuration tool across the platform and can reduce device setup and configuration time.

Simplified Setup & On-Going Maintenance

Direct Replacement for Multilin 169, 269, 269Plus and 369 Protection & Control Relays

The Multilin 859 is the only relay that offers a seamless, direct replacement for existing Multilin protection relays. Designed to fit the same mechanical cut and accept the same wiring connectors (applicable to 369 relays), the 859 provides a simplified replacement strategy – eliminating the need for drawing changes, re-wiring, and door modifications. While also significantly reducing any staff training requirements. Additional one-to-one wiring maps are available for other legacy Multilin motor protection relays, and automated setting file conversion and analysis tools ensure reduced configuration time and effort.

Retrofit Solutions

Upgrade seamlessly with the Multilin 859 from GE’s previous-generation motor relays; quickly swap from an existing Multilin 369 Relay without major changes.

The Multilin 859 fits the same mechanical cut-out and uses the same terminal blocks as existing Multilin 369 Motor Protection Relays. The 859 eliminates the need to modify existing cutouts and wiring, and does not require re-engineering or drawing changes. Migration tools further simplify the upgrade process, minimizing system downtime and commissioning time.

Easy 3-Step Process to Upgrade from 369 to 859, in as fast as 30 minutes

EnerVista 8 Series Setup Software provides automated setting file conversion. Once completed, the relay provides a graphical report to verify and call out any specific settings that might need attention

Simply unplug left and right terminal connectors and unscrew the upper and lower terminal wires to remove the 369 relay from the panel. No need to disconnect any of the field wiring*

Mount the new 859 relay into the switchgear, plug in the old terminal blocks and reconnect the upper and lower terminal wires – there is no need to make any cut-outs modifications or push and pull old cables

* The panel and all wiring must be deenergized and safety procedures followed
