01Protection Relays

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 20, 30 and 40 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 versatile hardware allows for application in many installations and a common relay management software (MiCOM S1) makes for easy configuration and application.

A standard and simple user interface across the range makes this ideal in any environment, from the more complex bay level control and mimic to the more simple LCD display and interrogation facility.

Numerous integrated communication protocols allow easy interfacing to most substation control or SCADA systems. The majority of MiCOM 30 and 40 series relays can be supplied with ethernet, to allow a full IEC 61850 solution for the substation.

THE MICOM RANGE OFFERS COMPREHENSIVE PROTECTION SOLUTIONS AT ALL POWER SYSTEM LEVELS SUCH AS :Generation
