Easergy MiCOM P746
Numerical Busbar Protection Relay Scheme (Centralized)
Easergy MiCOM P746 numerical busbar protection provides centralized complete protection for all voltages level up to extra high voltage busbar configurations. Models available: MiCOM P746
Easergy MiCOM P746 has proven techniques and dynamic topology processing algorithms, offer a combination of security, speed and sensitivity.
Simple configuration for centralized architecture
The Easergy MiCOM P746 differential busbar protection provides a centralized one box or three boxes architecture and is very simple to use:
It does not need to be deeply engineered and supports easy operation and maintenance of the busbar.
Fast, secure and easy to use
With a typical operating time of 15 ms with High Break High Speed contact option or 19ms with standard contacts, the Easergy MiCOM P746 protection is one of the fastest in its class.
Moreover, the trips can be synchronous or sequential, dynamically changing substation topology of the busbar is displayed on any PC with the substation real time dynamic monitoring tool.
With IEC61850-8.1 Edition 1 or Edition 2, Courier, DNP3.0, Modbus and IEC103 protocols, the Easergy MiCOM P746 is easily integrated in any substation system.
Latest communication protocols & Ethernet Redundancy
Fully Equipped with the latest communications protocols (IEC61850 Ed1 & Ed2 available in the same device, selection by setting).
Maximum availability and reliability of Ethernet communications thanks to the implementation of PRP/HSR standard redundancy protocols with an instantaneous recovery time (0 ms) in case of network failure.
Dual IP address allows the device to be connected to 2 independent communication networks (e.g, SCADA system network & Maintenance network)
Universal IRIG-B input (automatically detects modulated or unmodulated signal)
Major enhancement to Cybersecurity
Operational & Cyber Security, compliant to IEC 62351, helps protect installations with security based on embedded features such as Role Based Access Control (RBAC), Port Hardening, Security Logs and Access Traceability. The IED by default includes RBAC with different users defined and a Security Administrator.
Easergy MiCOM P746 REMOTE HMI PC APPLICATION SOFTWARE (Included in MiCOM S1 Studio User Software)
The Easergy MiCOM P746 remote PC HMI allows the user to display the Easergy MiCOM P746 Busbar topology, associated measured analogue quantities and DDB (digital data bus) status information such as circuit breaker and isolator positions and alarms.
