This paper describes an algorithm for detection of broken rotor bars based on MCSA enhanced with a set of motor conditions, collected by a protection relay to avoid a false declaration of an alarm due to rotor problems.
This paper presents the design and implementation details of a control system that detects an island condition in an industrial facility and executes a multi-tier load shed based on the load-generation balance.
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 will discuss the evolution of bus protection, focusing on distributed bus protection schemes and five key considerations in implementing IEC 61850 process bus distributed bus protection schemes in modern power systems.
This white paper outlines the interoperability of IEC 61850. Our practices, with several use-cases for interoperability within a multi-vendor environment are analyzed. The architecture/process at the device level and system level is proposed too.
Operators must have a relay lifecycle strategy to ensure device health and power system reliability. If you have an earlier generation UR, this paper guides you through a strategy and demonstrates how the UR minimizes typical device upgrade costs.
