Advanced Relaying Fundamentals
Tony Giuliante, President, ATG Consulting, Inc.
The seminar presents seven relaying concepts that are most often misunderstood by relay engineers.
Concept 1 deals with the physical meaning of positive and zero sequence line impedances. Students will learn the correct representation of zero sequence line impedance ZL0 = Zs + 2 Zm.
Concept 2 presents the derivation of symmetrical component transformations by using circuit equations and physical impedance values. The result will show the physical meaning of the line impedance matrix values.
Concept 3 derives the ground distance K factor and why there are so many different definitions used by relay manufacturers.
Concept 4 explores the Quad Characteristic and how to calculate test values for newer relay designs that use the compensated current (I phase + K*In).
Concept 5 shows why steady-state testing does not show the real expanding mho characteristic, or “Yes, Virginia, there is no such thing as zero source impedance.”
Case studies using CAPE will be used to explore concepts 3, 4, and 5..
Concepts 6 and 7 unravel the mysteries of CT saturation and transformer inrush.
Don’t miss this exceptional opportunity for professional development. Dynamic presenter Tony Giuliante, President, ATG
Consulting, Inc. and long-time analyst of trends in the protective-relaying industry will lead this exciting and practical full-day seminar.
