Overview
Essential details：F650-G-N-F-B-F-1-G-0-HI-C-6-E Multilin F650 feeder protection relay
The Multilin™ F650 has been designed for the protection, control and automation of feeders or related applications. The Multilin F650 provides high speed protection and control for feeder management and bay control applications, and comes with a large LCD and single line diagrams that can be built for bay monitoring and control for various feeder arrangements including ring-bus, double breaker or for breaker and half.
Designed with advanced communications options and detailed monitoring capabilities, the Multilin F650 provides advanced functionality, including high-performance protection, extensive control functions and flexible configuration capabilities. The Multilin F650 can also be used for a variety of applications other than feeder protection and control.

Over/Under Frequency Protection
The F650 offer six stages of overfrequency and underfrequency elements to improve network (grid) stability using voltage or frequency based loadshedding techniques. It also allows to provide back up protection and trip breakers directly when protecting feeders and other frequency sensitive power equipment.
Frequency Rate of Change Protection
Frequency rate of change (df/dt) elements included in the F650 provide protection against system disturbances through load shedding.
Wattmetric Zero-sequence Directional Applications include ground fault protection in solidly grounded transmission networks, grounded/ungrounded/resistor-grounded/ resonant-grounded distribution networks. The wattmetric zero-sequence directional element responds to power derived from zero-sequence voltage and current in a direction specified by the element characteristic angle. The angle can be set within all four quadrants and the power can be active or reactive. Therefore, the element may be used to sense either forward or reverse ground faults in either inductive, capacitive or resistive networks. The inverse time characteristic allows time coordination of elements across the network.
Breaker Failure and Control
The breaker failure function determines if a trip command sent to a breaker has not been executed within a selectable time delay. In the event of a breaker failure, the unit will issue an additional signal to trip the breakers connected to the same busbar, potential sources of fault current.
The F650 incorporates 3 levels of current and time, together with a trip without current unit, and an internal arc detection unit. The breaker failure unit has three levels: “Retrip” or “Supervision” used to generate a second trip signal to the corresponding breaker on which the initial opening has been executed, “High Level”, and “Low Level” used to executing complex protection schemes. The function can be initiated/blocked via digital inputs as well as communications.
The relay also provides for control of one or two breakers from faceplate pushbuttons, remote communications or contact inputs. A breaker pole discrepancy is included in the breaker control scheme. Breaker position is indicated by LEDs on the faceplate.
