This paper reviews key aspects of implementing traditional hard-wired solutions utilizing integrated multi-function relays and compares them with implementing the equivalent system using an IEC 61850-9-2 process bus solution.

This paper presents GOOSE messaging schemes to transmit data, and highlights the benefits of the three different types of GOOSE messaging systems available in the UR family of protection relays.

This paper presents the requirements for improved efficiency in all phases of engineering, maintenance, and operation, to support an increasing level of substation integration and protection.

This paper presents a case study for typically used redundant schemes and demonstrates some common implementation errors, pseudo redundancy, and illustrations of two relays providing inadequate redundancy.

This paper presents main risks and solutions for an overheated motor, as any motor failure will have the following cost contributors: repair or replacement, removal, installation and loss of production.

This paper outlines the need for the Power System Protection Systems (PSPS) also called System Integrity Protection Schemes (SIPS) and the resulting design requirements.

This paper outlines the technical implementation of technologies that enable Smart Grid practices.

This paper seeks to identify issues related to IEC 61850 standard deployment and to present solutions to meet industry trends and utilities' expectations.

This paper will discuss using relay functionality to fully monitor the protection and control system, which will identify problems within the system before they manifest themselves by miss-operation.
