Ballroom A

8:30 a.m. – Metering 101

Speaker: Dan Nordell, Xcel Energy

Metering can appear deceptively simple to the uninitiated. This tutorial will go back to the basics of electricity metering and will include practical discussions starting with fundamental principles up to and including recent state-of-the-art electronic metering applications. Emphases will include consideration of avoiding misapplication errors.

Room 1

8:30 a.m. – Energy Storage 101 Tutorial

Speakers: Chris Ruckman and Josh Tucker, Burns & McDonnell

When executing energy storage projects, there are a lot of pitfalls to avoid. From the permitting and interconnection process to engineering, procurement and construction, this presentation will cover challenges and lessons learned from previous energy storage projects and things owners can do to avoid these issues during the planning/execution phase. The topics covered will be related to battery technology, balance of plant design, HVAC/thermal management, electrical, fire detection and protection, and structural and construction topics.

Tutorial III

8:30 a.m. – Power System Protection 201: Line Relaying

Speakers: David Bisel and Josh LaBlanc, Schweitzer Engineering Laboratories, Inc.

Line relaying is a complicated topic with many details to consider. In this tutorial, participants will learn about line overcurrent relaying, and the need for "why" line distance protection is used to properly protect many transmission lines. High-speed relaying schemes are also reviewed, including pilot protection schemes and time domain protection. Participants will learn the following:

  • The basics of directional elements
  • Pilot protection schemes and the benefits each provide
  • How to apply zone distance elements for short lines
  • Line current differential basics
  • Time domain protection basics
  • Line protection concepts near inverter-based resources (IBRs)

Tutorial IV

Room 4

8:30 a.m. – Transformer Testing 101: WR, TTR, PF, SC

Speaker: Ravi Raj Gupta, Megger

Tutorial will go over the various transformer tastings. Mainly: winding resistance (WR), transformer turns ratio (TTR), power factor (PF) testing, and Short Circuit (SC) impedance. We will go over the concepts, best practices, what to look out for, and result interpretation and how this data can be used as a predictive tool for the health of the transformer.
