Access Control

Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. Password security is an optional feature of the 3 Series which can be setup using the SR3 EnerVista Setup software. The password system has been designed to facilitate a hierarchy for centralized management. This is accomplished through a Master level access password which can be used for resetting lower level access passwords and higher level privileged operations.

Auditing and Reporting

With the Security Audit Trail reporting feature, available in GE Vernova’s ViewPoint Monitoring software, operators are able to obtain Event logging reports of key activities such as configuration changes. These pre-formatted reports can be used to help ensure device and protection system integrity and perform forensic auditing of activities and changes for compliance.

Inputs and Outputs

The 339 features the following inputs and outputs for monitoring and control of typical motor applications:

• 10 contact Inputs with programmable thresholds
• 7 Outputs (2 Form A, 5 Form C) as standard and 4 Outputs (1 Form A, 3 Form C) when internal RTD option is selected
• 5 Form C output relays

Drawout & Non-Drawout Construction

The 339 is offered in both a drawout or a non-drawout construction. In the drawout case design the 339 simplifies installation and improves site safety as the need to open switchgear doors or rewire the device after testing is eliminated.

The 339 protection relay chassis used with a draw out relay is available separately, for use as a partial replacement or in test environments. The draw out relay with no chassis is also available to order as a spare unit.

Application Flexibility & Ease of Wiring 

Removable terminals ease wiring and in-system testing or troubleshooting.

Optional RTD

Multilin 869 motor protection relay functional block diagram

High-Inertia Load Applications

The voltage dependent overload curve feature in Thermal Model is tailored to protect motors which 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 869 to distinguish between a locked rotor condition, an accelerating condition and a running condition.

VFD-Driven Motor Applications

The Multilin 869 provides protection for motors fed through VFDs (Variable Frequency Drives). A wide range of the frequency tracking (3-72Hz) allows the 869 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 higher harmonics due to VFD to achieve the 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 the security.

Additionally, users may indicate a starting VFD frequency that helps the device to track the motor frequency faster and therefore accurately measures the phasor quantities, which, otherwise, could cause delayed or false protection operation of the protection.

Cyclic Load Motor Applications

Input currents of a motor driving cyclic load can vary between very low to above 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 made 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

Synchronous Motor Applications

869 provides functions essential to protect the synchronous motor during asynchronous operation while startup, during normal and overload operations and under fault conditions. In addition to stator protection and control, it provides protection and monitoring of exciting rotor during pull-out or loss of synchronism condition with elements like Out-of-Step, Loss-of-Field, Reactive Power, and Power Factor. With its well established and matured Thermal Model, it prevents overheating of both stator and rotor windings during both synchronous and asynchronous operation. During asynchronous operation or startup, the thermal model with VD (voltage dependent) function provides protection against excessive heating in the damper winding due to stalled or locked rotor conditions.

The Multilin 869 offers an integrated, cost effective Monitoring and Diagnostics features that leveraging existing relay data without the need for additional devices, sensors, wiring or training.

• 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 can help reduce unplanned downtime and energy consumption - maximizing motor output and life.
• Motor monitoring & diagnostic features include stator turn to turn fault, broken rotor bar detection, roller bearing faults, foundation looseness, eccentricity, and misalignments. Using advanced Motor Current Signature Analysis (MCSA), the 869 continuously analyzes the motor current signature and based on preset algorithms will determine when an electrical, thermal or mechanical fault / failure condition exists in the motor.

Watch our Tech Talk: Electrical Signature Analysis for a Real-Time Motor Condition Monitoring System

The 869 implements a patented environmental monitoring system that measures and provides operating condition information. Reliable and secure operation of the 869 relay and other electronic devices in the vicinity may be affected by environmental factors. The 869 relay has been designed to meet or exceed all required industry standards. Some operating conditions may be beyond those standards and reduce total lifespan of the device.

The Multilin 8 Series supports an integrated arc flash module providing constant monitoring of an arc flash condition within the switchgear, motor control control centers, or panelboards. With a 2ms protection pass, the 8 Series is able to detect light and overcurrent using 4 arc sensors connected to the 8 Series relay. In situations where an arc flash/fault does occur, the relay is able to quickly identify the fault and issue a trip command to the associated breaker thereby reducing the total incident energy and minimizing resulting equipment damage.

Self-monitoring and diagnostics of the sensors ensures the health of the sensors as well as the full length fiber cables. LEDs on the front panel display of the 869 can be configured to indicate the health of the sensors and its connections to the relay.

The 869 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.
