C60 Breaker Monitoring and Control / C95 Bay Control Unit for Substation and Industrial Automation

​

The C60 breaker and C95 bay controllers are a substation-hardened-devices that provide a complete integrated package for the protection, control, and monitoring of circuit breakers or bay. The C60 and C95 support dual-breaker busbar configurations such as breaker-and-a-half or ring bus arrangements. Signals from up to 4 sets of CT’s can be brought into the C60/C95 via conventional wiring or process bus for internal summation, which is advantageous by still having the individual currents available for metering and the additional protection elements that operate on individual currents.

Protection & Control

​

The C60 breaker and C95 bay controllers are a substation-hardened-devices that provides a complete integrated package for the protection, control, and monitoring of circuit breakers or bays. The C60/C95 support dual-breaker busbar configurations such as breaker-and-a-half or ring bus arrangements. Signals from up to 4 sets of CT’s can be brought into the C60/C95 for internal summation which is advantageous by still having the individual currents available for metering and additional protection elements that operate on individual currents.

​

The C60/C95 provide fast and deterministic execution of programmable logic and extensive I/O options that are necessary for substation automation applications.

All of the necessary control logic functions are available for creating automated breaker control schemes such as the popular main-tie-main scheme using a single C60 / C95 device.

Communications

​

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

 

Advanced Communications

The C60/C95 provide advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner.

The C60/C95 support the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.

Software & Security

​

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:

Secure FW upgrade

​

UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices.

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 C60 / C95 controllers. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the C60/C95 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.
