MiCOM Substation Applications

MiCOM Substation / Feeder Applications

The MiCOM range of relays offers varying levels of functionality and hardware options to best suit the protection requirements and allows the customer to choose the most cost effective solution for their application.

The versatile hardware allows for application in many installations and a common relay management software (MiCOM S1 Studio) makes for easy configuration and application.

Basic Feeder Protection Relays — MiCOM 10 Series

The 10 series hardware platforms are the building blocks of the MiCOM protection relay range providing the capability for a wide variety of protection, control, measurement, monitoring and communication functions.

The MiCOM P11x relays are suitable for all the applications where overcurrent and/or ground fault protection are required. P11x can be applied to medium and low voltage electrical systems as an optimized and cost-efficient solution tailored to user’s needs.

Standard and Advanced Feeder Protection Relays — MiCOM 30 and 40 Series

  • Easergy MiCOM P132 offers a flexible and powerful feeder management device housed in a 4U case in 24TE, 40TE or 84TE widths. Easergy MiCOM P132 offers bay control for up to 3 devices and a library of 80 pre-engineered templates to reduce engineering time.

  • Easergy MiCOM P139 one-box solution is the most advanced in the range. It’s available in 40TE or 84TE width, 4U case sizes. It offers bay control for up to 10 devices. It uses a pre-engineered library of up to 300 templates for efficient engineering and commissioning.

  • Easergy MiCOM P14x Feeder Management and Overcurrent Protective Relays are especially suitable where a complete or advanced power system protection scheme solution is required.

The following models are available:

  • Easergy MiCOM P141 – Feeder management relay

  • Easergy MiCOM P142 – Feeder management with integrated Autoreclose

  • Easergy MiCOM P143 – Feeder management, integrated Autoreclose and Check Synchronism

  • Easergy MiCOM P145 – Feeder management, Autoreclose, Check Synchronism and Enhanced operator control functions
