　　F650-G-N-A-B-F-2-G-1-HI-C-E Other names:

　　Motor protection device F650-G-N-A-B-F-2-G-1-HI-C-E

　　F650-G-N-A-B-F-2-G-1-HI-C-E relay protection device

　　Digital Rack Controller F650-G-N-A-B-F-2-G-1-HI-C-E

　　The Multilin F650 is designed specifically for the protection, control, and automation of feeders or related applications. The Multilin F650 feeder protection relay provides high-speed protection and control for feeder management and interval control applications, and is equipped with a large LCD and single line diagram, which can be used to build interval monitoring and control for various feeder arrangements, including ring busbars, double circuit breakers or circuit breakers, and half circuit breakers.

　　Main advantages

　　A comprehensive and flexible protection and control device suitable for feeder applications

　　Increase system uptime and improve stability through load shedding and transfer schemes

　　Advanced automation features that provide customized protection and control solutions

　　Human Machine Interface (HMI) with graphical LCD, programmable buttons, and convenient keys for selecting settings menus and submenus

　　Adopting a modular pull-out structure to reduce replacement time

　　Reduce troubleshooting time and maintenance costs by utilizing IEEE 1588 (PTP), IRIG-B, and SNTP time synchronization (with two different SNTP master stations configured), event reporting, waveform capture, and data logger

　　Simplify system integration, support serial and Ethernet interfaces, and communicate with multiple protocols

　　Embedded IEC ® The 61850 protocol (and supports version 2) IEC 60870-5-103/104、IEC 62439/PRP/HSR、IEEE 802.1D/RSTP

　　Verified interoperability and KEMA 61850 2nd edition certification

　　Application

　　Main or backup protection and control of direct grounding, high impedance grounding, or resonant grounding system feeders

　　Bus locking/interlocking scheme

　　High speed fault detection of arc flash

　　Transfer Plan (Application for Bus Transfer Plan)

　　Load shedding scheme based on voltage and frequency factors

　　Distributed Generation (DG) interconnection protection, including active and passive islanding prevention

　　The F650 provides high-speed protection, feeder management, and interval control applications, including overcurrent protection, instantaneous and time overcurrent functions that can be used for phase, neutral, ground/sensitive ground, and negative sequence currents. A. Provides various time curves, including IEEE/ANSI ®、 IEC A/B/C/Long time inverse/Short time inverse, GE IAC, I2t, timed rectifier curve, and four user programmable curves. Directional supervision can be carried out during the stage, including neutral, grounding, and sensitive grounding currents. The neutral/ground directional component can be programmed to operate at zero sequence voltage, ground sensitive current, or dual polarization.

　　Overfrequency/underfrequency protection

　　F650 provides six stages of overclocking and low-frequency element improvement network based on voltage or frequency (grid) stability load shedding technology. It also allows for providing backup protection and tripping circuit breakers to directly protect feeders and other frequency sensitive electrical equipment. The protection function contained in the frequency change rate protection (df/dt) element F650 can prevent interference caused by load shedding. The zero sequence directional application of wattmeters includes ground fault protection in firmly grounded transmission networks, grounded/ungrounded/resistor grounded/resonant grounded distribution networks. The zero sequence directional component of this wattmeter responds to zero sequence power by specifying the characteristic angles of the voltage and current components in the specified direction. The angle can be set in all four quadrants, and the power can be active power or reactive power. Therefore, elements can be used for forward sensing or for reverse grounding faults in inductors, resistors, or resistive networks. The opposite time characteristic allows time to coordinate the elements in the network.
