Engineering ethics are essential to retain the public's trust with electric power providers. This will highlight practical ethical behavior and case studies. – Fundamental

1:00 p.m.



RTU Life Extension and Migration Strategy, Ernest Gust, Xcel Energy
Upgrading obsolete RTUs without touching the original field wiring using plug-and-play components and connectors in less than one day. − Intermediate


Integrating Roles Within Electric Utilities to Achieve Arc Flash Safety, Neil Stiller, Bob Cooke, Rochester Public Utilities
Arc flash safety is an organization-wide effort to build understanding, establish standards, modify work practices, train, and maintain the attitudes of safety and compliance. Current and evolving engineering, training, and business practices at Rochester Public Utilities will be discussed. − Intermediate

Delivery Systems

Transmission Interconnection Planning for the Country’s Largest Manufacturing Facility— In Less than Four Months, Chengyue Guo, Jui-Ning (Joey) Cheng, Michael Marz, American Transmission Company
In October 2017 Foxconn announced a 200 MW (potentially 400 MW) manufacturing facility for full operation in January 2020. How ATC developed the interconnection project, including regulatory submission in January 2018, is described. − Intermediate

Relaying I

Beyond the Knee Point: A Practical Guide to CT Saturation, Michael Thompson, Schweitzer Engineering Laboratories, Inc.
Current transformer (CT) saturation, while a fairly common occurrence in protection systems, is not often clearly understood by protective relay engineers. This paper forgoes the usual physics equations to describe how CTs saturate in a simple and intuitive way. − Intermediate

1:45 p.m.


Introduction to IEEE 1818 – IEEE Guide for the Design of Low-Voltage Auxiliary Systems for Electric Power Substations, Joe Gravelle, Xcel Energy

A new IEEE guide has been created by the Substations Committee D9 Group that considers AC and DC system components from the sources to the distribution. Substation system design recommendations, reliability requirements, load characteristics, and distribution methods are discussed. − Fundamental


Practical Operational Environmental Security, Joe Peterson, Warren LaPlante, Minnesota Power

The operational world has evolved to an integrated network of intelligent devices that requires attention to physical and cybersecurity measures to operate effectively, safely, and reliably. Practical approaches and available resources will be discussed. − Intermediate

Delivery Systems

MISO Generation Interconnection Process and Challenges, David Brauch, Midcontinent Independent System Operator (MISO)

With approximately 92 gigawatts of generation interconnection requests, MISO faces process challenges. This presentation will provide a fundamental overview of MISO’s generator interconnection process and future challenges. − Fundamental

Relaying I

Improving Transformer Protection, Wayne Hartmann, Beckwith Electric

Power transformers play a critical role in the power system. These transformers are subject to internal short circuits, external short circuits, and abnormal operating conditions. Several protection challenges to power transformers will be explored, and methods to improve the protection provided. − Intermediate
