This application note shows that when the time constants are properly matched, the relay works correctly on cyclic loads. It also provides practical examples of how to set up the Multilin 469 relay.
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.
Digital protection relays are made to provide reliability, selectivity and speed to power system protection engineers. This paper focuses on local breaker failure protection, covering the basics and enhancements of BF detection.
The modern technologies utilized by microprocessor based protective relays provide the means to accelerate the extinction of the arc produced by short circuits where the air is the conducting material.
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.
As the electrical network has evolved, substations have kept pace, bringing together technologies and strategies to improve the network, resulting in intelligent digital substations.
This paper will explore three key Smart Grid functions (Delivery Optimization, Demand Optimization and Asset Optimization) with the strongest business case justification.
This paper discusses how, in the electric power industry, Work Process Management can provide an environment to control, analyze, and audit activities across multiple departments.
