The Multilin 859 Motor Protection System, a member of the Multilin 8 Series protective relay platform, is designed for the protection, control and management of medium and large power rating induction motors. It has also been purpose built as a direct replacement for GE Vernova’s existing range of Multilin motor protection relays including the 169, 269, 269Plus, and 369 devices.
Based on the same field proven hardware and protection and control algorithms of the Multilin 8 Series, the 859 delivers advanced features including high-speed protection, customizable programmable logic, and advanced motor monitoring and diagnostics - all in a fixed mount, slim design.
With extensive communication capabilities the 859 easily integrates into new or existing process control systems, enabling operationally focused motor management and control
To simplify the migration and upgrade from existing Multilin 169, 269/269Plus, and 369 protection relays, the 859 has the same cutout and depth. In the case of replacing a 369 relay, the 859 has the same terminal arrangement, eliminating the need to change field wiring. In the case of other relays, detailed one-to-one wire maps and setting file conversion tools are provided to significantly simplify the upgrade process. Learn More
The Multilin 859 Motor Protection System is a protection device for managing, protecting and controlling medium to large horsepower motors.
With a fast protection pass, running every 1/8th of a cycle, the 859 relay provides fast current, voltage, power and frequency protection elements; reducing stress on the motor. The Multilin 859 supports the latest standard communications protocols, including IEC 62439/PRP and IEC 61850 Ed. 2 ; facilitating easy integration into new and existing SCADA/DCS networks.
The voltage-dependent overload curve feature in the Thermal Model protects motors that are used in high-inertia-load applications. Voltage is continually monitored when the motor is started and during acceleration. The thermal-limit curve is then adjusted accordingly. This enables the Multilin 859 to distinguish between a locked-rotor condition, an accelerating condition, and a running condition.
The Multilin 859 provides protection for motors fed through VFDs (Variable Frequency Drives). A wide range of the frequency tracking (3-72 Hz) allows the 859 to track the motor frequency and adjust its sampling rate to accurately measure phasors. An advanced algorithm allows switchable current and voltage tracking in case VFD is bypassed.
Thermal protection also considers the extra heating generated by the greater harmonics due to the VFD, to achieve an accurate response to the actual motor heating. RMS currents fed to the various motor-protection elements are further processed through the averaging filter to eliminate oscillations in current signals to ensure security.
Additionally, users can indicate a starting VFD frequency that helps the device track the motor frequency faster. Therefore, the 859 accurately measures the phasor quantities, which, otherwise, could cause delayed or false protection operation.
Input currents of a motor driving cyclic load can vary between very small to greater than the maximum allowable current during a load cycle. Variation in current magnitude results in motor heating and cooling depending on the heat and cooling time constants. Thermal overload protection response is adaptive to the cyclic load based on the cooling time constants. In addition, to provide more accurate overload thermal model response to cyclic load, the input currents to the thermal model are averaged over the settable duty-cycle interval. With a reciprocating-load application, the number of cycles to average can be determined from current waveform capture using the Oscillography/Datalogger features in the GE Vernova motor-protection relays
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.
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:
The 859 continuously and proactively monitors the motor for Thermal Capacity Used (TCU) to provide early warning of thermal stresses including:
Without the need for additional sensors or probes, the 859 utilizes GE Vernova's patented Electrical Signature Analysis (ESA) / Motor Current Signature Analysis (MCSA) to identify mechanical abnormalities in the motor including:
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.
Providing several Ethernet and serial port options, dual independent Ethernet Ports, and support for a wide range of industry standard protocols, the 859 enables easy, direct integration into DCS and SCADA systems. The 859 supports the following protocols:
The 859 has two interfaces as USB front port and Wi-Fi for ease of access to the relay. Wi-Fi Connectivity:
The 859 cyber security enables the device to deliver full cyber security features that help operators to comply with NERC CIP guidelines and regulations.
Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.
Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication.
Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This will enable integration with established SEM (Security Event Management) systems.
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.
