850 Feeder Protection SystemDistribution FeederSimplified Management - Platform Based SolutionWith support for up to 8 CT inputs & 2 sets of 4 traditional VT inputs, the850 can be used for 2 feeders or feeders with 2 sets of voltage inputs,simplifying system architectures and operational costs. Reduced training needs Standardized part number across systems Harmonized look and feel, operational experienceThe 850 offers redundancy with the same number of devices, enabling:Protection & ControlAs part of the 8 Series family, the Multilin 850 provides superior protectionand control. The 850 offers comprehensive protection and controlsolutions for incoming, outgoing bus-tie/bus-coupler feeders. It containsa full range of selectively enabled, self-contained protection and controlelements.Single feeder, dual voltageThe voltage and frequency protection functions detect abnormal systemconditions, potentially hazardous to the system. Some of these conditionsmay consist of over and undervoltage, over and underfrequency, andphase reversal.Fast UnderfrequencyThe 850 has an 8 stage Fast Underfrequency element that measuresfrequency by detecting the consecutive voltage zero crossings andmeasuring the time between them. The measured frequency has a rangebetween 20 to 70 Hz. This is useful for performing fast load-sheddingwhen frequency variations from unbalance conditions arise due to: Inadequate load forecast or deficient generation capacity programming. Busbars, generator group or interconnection feeders trip. System splits into islands.Dual feederFlexCurves For applications that require greater flexibility, FlexCurves can be used todefine custom curve shapes. These curves can be used to coordinate withother feeders to achieve fault selectivity.RTD ProtectionThe Multilin 850 supports up to 13 programmable RTD inputs that can beconfigured for an Alarm or Trip.The RTDs can be assigned to a group for monitoring ambient temperaturesor any other desired temperature. The RTD voting option gives additionalreliability to ignore and alarm for any RTD failures.Integrated Arc Flash ProtectionRedundant feederArchitecture Simplification - Reduced Number of Devices Less capital cost Less O&M costMean Time to Repair - Less than 15 minutes Field swappable PSU Draw out construction Ready to consume service reportsExtended Asset and Relay LifeThe Multilin 8 Series supports an integrated arc flash module providingconstant monitoring for an arc flash condition within the switchgear,motor control centers, or panelboards. With a 2ms protection pass,the 8 Series is able to detect light and overcurrent using 4 arc sensorsconnected to the relay. In situations where an arc flash/fault does occur,the relay is able to quickly identify the fault and issue a trip command tothe associated breaker thereby reducing the total incident energy andminimizing resulting equipment damage.Self-monitoring and diagnostics of the sensors ensures the health of thesensors as well as the full length fiber cables. LEDs on the front paneldisplay of the 850 can be configured to indicate the health of the sensorsand its connections to the relay.

850 Feeder Protection SystemBreaker Health MonitoringWANT TO LEARN MORE?EXPLORE IN 3DThe breaker is monitored by the relay not only for detection of breakerfailure, but also for the overall “breaker health” which includes: Breaker close and breaker open times Trip circuit monitoring Spring charging time Per-phase arcing current Trip countersAll algorithms provide the user with the flexibility to set up initial breakertrip counter conditions and define the criteria for breaker wear throughouta number of set points.MV SwitchgearMultilin 8 SeriesFast, reliable arc flash protection with integrated light based arc flashsensors. This delivers detection in as fast as 2 msec, reducing the costsassociated with equipment damage and unplanned downtime.Inputs and OutputsThe 850 provides a max of 57 Digital inputs and 22 Digital outputs with anoption for 7 Analog Outputs (dc mA), 4 Analog Inputs (dc mA), and 1 RTDinput. The configurable analog inputs can be used to measure quantitiesfed to the relay from standard transducers. Each input can be individuallyset to measure 4-20 mA, 0-20 mA or 0-1 mA transducer signals.Breaker Health Reporting assists Condition-Based Maintenance andsavings in Operational CostsAdvanced AutomationThe Multilin 850 incorporates advanced automation capabilities whichexceed those found in most feeder protection relays. This reduces theneed for additional programmable controllers or discrete control relaysincluding programmable logic, communication, and SCADA devices.Advanced automation also enables seamless integration of the 850 intoother protection or process systems (SCADA or DCS).Monitoring & DiagnosticsFlexElements Environmental MonitoringFlexElement is a universal comparator, that can be used to monitorany (analog) actual value measured or calculated by the relay, or a netdifference of any two analog (actual) values of the same type.The 850 has an Environmental Awareness Module (EAM) to recordenvironmental data over the life of the product. The patented modulemeasures temperature, humidity, surge pulses and accumulates theevents every hour in pre-determined threshold buckets over a period of15 years. This data can be retrieved using the EnerVista Setup Software.This report helps identify the operating condition of the installed fleet sothat remedial action can be taken.The element can be programmed to respond either to a signal level or to arate-of-change (delta) over a pre-defined period of time.This can be used to generate special protection or monitoring functionswhich allow the user to flag a user-defined abnormality to give bettervisibility to a certain condition.The Multilin 850 includes high accuracy metering and recording for all ACsignals. Voltage, current, and power metering are built into the relay as astandard feature. Current and voltage parameters are available as totalRMS magnitude, and as fundamental frequency magnitude and angle.FlexLogic FlexLogic is the powerful programming logic engine that provides the abilityto create customized protection and control schemes, minimizing theneed for and associated costs of auxiliary components and wiring. UsingFlexLogic, the 850 can be programmed to provide the required tripping logicalong with custom scheme logic for feeder control interlocking schemeswith adjacent protection (for example, preventing sympathetic tripping ofhealthy feeders), and dynamic setting group changes.4GEGridSolutions.com
