Areva T&D's latest software version, including major enhancements, is now available in the MiCOM P12x range of numerical overcurrent protection.
For many years, the MiCOM P12x range of numerical overcurrent protection has offered a cost-effective solution for MV feeders and HV backup protection. Because of the new v11 software, based on phase II hardware, MiCOM P12x is now more powerful, more flexible and more reliable.
Evolutions in v11 software include:
eight independent Boolean logic equations (NOT, AND & OR) with up to 16 parameters each
Multi-assignable digital inputs which can also be mapped to any output contact
DNP3 protocol implementation
Boosted records capability with 250 events and 25 fault records
Time synchronization through a digital input
Inrush blocking function
Under/over frequency protection (81U/O) in P127
Three phase overpower protection (32) in P127
The MiCOM P12x protection range still incorporates the following features:
Front EIA 232 communication port on all MiCOM P12x to download or upload setting files with MiCOM S1
Output contact relays with improved dielectric withstand and breaking capacity
A non-volatile flash memory to store all protection records (disturbance, events and faults)
A multi-language Human Machine Interface
An extended power supply range from 48 to 250 Vdc/ac
