    Symmetrical Components Made Easy – Part 2

    In the last post we examined and calculated the symmetrical components in a non-faulted, three-phase electrical power system.  This post expands on the same process of using phasor diagrams to describe, illustrate, visualize and calculate the three symmetrical components: Positive Sequence, Negative Sequence and Zero Sequence.  An examination of a phase to neutral (also referred

    How to test IEC 61850 / GOOSE using the MTS-5100

    Modern electric power utilities have been increasing their standardization on IEC 61850 communications within substations in recent years. It is becoming common for substations to use IEC 61850 GOOSE (Generic Object Oriented Substation Events) as a replacement for individually-wired signals between protective relays and other equipment. GOOSE messages allow low-latency, real-time transmission of events over an Ethernet
