Protection & Control
The F650 feeder protection relay provides high speed protection and control for feeder management and bay control applications, including:
Fault locator, fault and event recorder
Comprehensive breaker monitoring
High resolution oscillography and Data Logger, with programmable sampling rate
Metering: V, I, Hz, W, VA, PF
Demand: Ia, Ib, Ic, Ig, Isg, I2, MW, MVA
Monitoring & Metering
The F650 provides advanced monitoring and metering that includes:
VT Fuse Failure
Use the VT Fuse Failure feature to issue an alarm and/or to block voltage driven protection functions that can operate incorrectly due to an abrupt partial or total voltage loss. This loss is caused by the voltage transformers secondary circuit protection fuse failure. Different methods are used to detect the different types of VT fuse failure.
Trip Circuit Monitoring
F650 can be used to monitor the integrity of both the breaker trip and closing coils and circuits. The supervision inputs monitor both the battery voltage level, while the outputs monitor the continuity of the trip and/or closing circuits, by applying a small current through the circuits.
Ia, Ib, Ic, Ig, Isg, Va, Vb, Vc and Vx signals are available locally and remotely and can be stored in the oscillography record or data logger.
Event Recording and Oscillography
The F650 is capable of storing 479 time-tagged events (1 ms tagging), to help with troubleshooting. The trigger point, the channels, and sampling rate of the oscillography files are user programmable features. Up to five seconds at maximum sample rate can be stored.
The F650 incorporates the industry-leading communication technologies making it one of the easiest and flexible feeder protection relays for use and integration into new and existing infrastructures.
The F650 provides optional Parallel Redundancy Protocol (PRP), High Availability Seamless Ring (HSR) (IEC 62439-3) and also Rapid Spanning Tree Protocol (RSTP) (IEEE 802.1D) to increase network availability and reliability for critical applications.
The F650 supports popular industry leading standard protocols enabling easy, direct integration into electrical SCADA and HMI systems. The protocols supported by the F650 include:
IEC 61850 Edition 2
PRP & HSR (IEC 62439-3)
RSTP (IEEE 802.1D)
IEEE 1588 (PTP) for time synchronization
The F650 provides integration with 61850 standard edition 2. IEC 61850 allows for the seamless connection of IEDs from multiple vendors. In addition to device interoperability, these protocols are designed to control the substation via a LAN instead of through discrete wiring to an RTU.
Example of redundant HSR and PRP Architecture
Redundancy protocols can be used for various networking architectures including combined PRP / HSR technologies
The EnerVista Suite is an industry-leading set of software programs that simplifies every aspect of using the F65 relay. The EnerVista suite provides all the tools to monitor the status of your the protected asset, maintain the relay, and integrate information measured by the F650 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the 650 Setup software included with every F650 relay, to carry out postmortem event analysis to ensure proper protection system operation.

Security - Enabling NERC CIP Compliance
Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The 650 Family provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.
Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity.control factor that can lock or unlock a device for configuration changes and other modifications.
Auditing and Reporting
With the Security Audit Trail reporting feature and support for Event logging of key activities such as configuration changes, Multilin devices can help ensure device and protection system integrity, and perform forensic auditing of activities and changes for compliance.
