Engineering Webinar Series: All 12 Webinars
January 10 December 12, 2023
Who Should Attend:
Engineering personnel and others who would benefit from an understanding of current electric utility engineering principles and practices.
The engineering webinar series is comprised of 12 webinars from January through December 2023. Descriptions for each webinar can be found below. Webinars can be taken individually or as an entire series; by registering for the full series, you will receive all 12 webinars at a discounted price. Group pricing is also available.
2023 NESC Update (Jan. 10)
We will address the major changes in the NESC; the 2023 NESC becomes effective February 2023.
Introduction to Substation Design/Operation (Feb. 14)
We will discuss basic layout of substations, purpose of major components, use of transfer buses, and bypass switching. Other issues to be addressed are SPCC options, lightning protection, grounding, and access.
Storm Hardening for Distribution Systems (March 14)
The trend in the industry is to design more resilient systems that go beyond basic reliability. We will review techniques for hardening distribution systems, including increasing weather loading, increasing load factors, upgrading key poles on the system, and undergrounding.
Inspection of In-Service Wood Poles (April 11)
We will review the requirements of the NESC as it relates to pole inspections, and address inspection cycles and methods. Estimating reduced strength of wood poles will also be covered.
Overview of Double Circuit Design (May 9)
While many of the techniques used for single circuits can be applied to double circuits, this session will review unique issues and design considerations applicable to double circuit design, including spacing between crossarms, guying challenges, and framing options.
Mitigation of Animal-Caused Outages (June 13)
Reliability is becoming more important in today’s electronic dependent environment, and animal-caused outages is one area where the utility can improve distribution reliability. We will discuss mitigation for outages caused by animals, such as squirrels and birds, and also talk about substation protection.
Fire Mitigation for Distribution Lines (July 11)
To mitigate the risks of wildfires caused by the electric distribution system, many utilities are fire hardening their systems. We will discuss the electric distribution system components and line equipment and their potential risk for wildfires. We will also review changes in standards for the construction and maintenance of the distribution grid to reduce the risks of wildfires.
Three-Phase, Pad-Mounted Transformers (Aug. 8)
Three-phase, pad-mounted transformers can be expensive items for an electric utility so it is important to understand the industry standards that apply to them, as well as many of the different options available in the marketplace. We will also review the specification and application of these units.
Harmonics and Effect on Power Quality (Sep. 12)
Many power quality issues stem from harmonics often introduced on the power system from inverters, VFD, and other devices. Attend this session to learn about harmonics, IEEE 519, and how to use a k factor in specifying transformers subject to high harmonic connections.
Overhead Conductor Characteristics (Oct. 10)
The purpose of distribution lines is to move energy from one place to another through conductors; the key to reliable, safe, and efficient design is having a good working knowledge of overhead conductors. Therefore, we will address electrical and mechanical properties of primary overhead conductors.
Designing Underground for New Subdivisions (Nov. 14)
Designing underground distribution differs from designing overhead distribution in terms of resiliency of the system. We will review common underground design criteria such as methods for design in underground subdivisions and commercial developments; routing of cable systems; and use of conduit, burial depth, and common errors in design. We will also address single contingency outage and overcurrent protection scheme along with limiting factors of system components.
Interconnection of Distributed Generation (Dec. 12)
As distributed generation becomes ubiquitous, electric utilities must become more adept at interconnecting these sources to the distribution system. In this session, we will focus on the screening methods for smaller DG units, the impact of smart inverters, and detailed system impact studies if screening fails.
Webinar recordings can be made available to registrants who are unable to attend live.
All webinars in this series will be held from 8-9:30 a.m. Pacific Time. Attendees will be admitted 15 minutes before the webinar begins.
