Monitoring & Diagnostics

The N60 includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.

The N60 is the single point for protection, control, metering, and monitoring in one integrated device that can easily be connected directly into DCS or SCADA monitoring and control systems like Viewpoint Monitoring as shown.

FlexLogic™

FlexLogic is the powerful UR-platform programming logic engine that provides the ability to create customized protection and control schemes based on information measured locally by the N60 and received from remote N60s sent to it over the communications network. With FlexLogic, the N60 can use the status of measured inputs, along with the output of the protection elements, FlexElements and FlexMath summators, in Boolean logic equations to perform automated functions for customized special protection schemes.

The N60 contains FlexLogic and FlexMath equations that allow the creation of automated wide area protection and control schemes, remedial action schemes, and other special protection applications.

Key Features

Complete IEC 61850 Process Bus solution providing resource optimization and minimizing total P & C life cycle costs

• Three independent 100Mbps Ethernet ports enable purpose specific LAN support that eliminates latency effect of heavy traffic protocols on mission critical communication services
• Embedded IEEE 1588 time-synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
• Direct I/O secures high-speed exchange of binary data between URs
• Increase network availability by reducing failover time to zero through IEC62439-3 PRP, HSR or dual HSR support

Cyber Security - CyberSentry™ UR (FW v7.4xx)

CyberSentry enables UR devices to deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features:

Password Complexity

Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available.

AAA Server Support (Radius)

Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.

Role Based Access Control (RBAC)

Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication. 

Event Recorder (Syslog for SEM)

Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems.

EnerVista™ Software

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the N60 relay. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the N60 into DCS, SCADA monitoring or WAM systems.
