MiCOM P111 relays provide features for easy adaptation to different applications and operating conditions. The P111 can be fully configured manually, without using setting software. Alternatively, MiCOM S1 Studio setting software allows configuration parameters to be modified for a specific application via the USB port. IEC 60870-5-103 and Modbus RTU integrated communication protocols are available for flexible integration into most substation control or DCS systems. Close and Trip commands can be executed via functional key on the front panel, default menu window, DCS/SCADA system (RS485) or configured binary input. Three level password gives proper rights for secure maintenance of the relay. As a device housed in a small sized flush-mountable case, the P111 can be easily installed in all modern, dimension-focused switchgear panels. The relay can be also considered as a cost-effective answer to retrofit demands of older substations.

Selectable measuring criteria: True RMS and/or fundamental frequency (Fourier) current measurements allow to increase selectivity and adapt to the application.

Application:
The MiCOM P111 numerical overcurrent protection relays provide an optimized and cost-efficient solution.

Typical applications are:

• Utility and industrial substation fitted with cost-optimized MV switchboards
• Retrofit relays of old technology, particularly during installation of DCS systems
• Transformers, incomers, bus couplers, capacitor banks, overhead lines and underground cables on MV systems
• Neutral system protection (insulated, solid and resistance earthed)
• LV substations
