      Modern power systems are under increasing constraints in their ability to transmit power from generation facilities to major load centers, and are forced to operate closer to their natural stability limits. Under these conditions, the critical clearing angle – and corresponding critical clearing time – become progressively smaller and there is an increasing need to minimize the fault clearing time on these constrained circuits.
    The D90Plus is ideally suited for application on circuits where fast fault detection and small breaker failure margin are required. The D90Plus allows transmission limits to be maintained or even increased while respecting the transient stability limits of the power system.

    Access Control
    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 UR and URPlus families provide separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, they also provide a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.
     
    Intrusion Detection
    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, and a 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.
