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 2021. 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.
Fundamentals of Guys and Anchors for Overhead Distribution Lines, January 12, 2021
When a pole is unable to support wind loading and conductor tension, guys and anchors are required. This webinar focuses on the understanding of the forces to be supported by guys and anchors. Further, strength-rating of the guy and anchor assemblies are required with emphasis on NESC requirements. The effect of guys on the strength of assembly will be addressed.
Unique Guying Applications, February 9, 2021
Most down guy situations are simple, straight-forward applications to support wind loading and conductor tension, but exceptions are inevitable. This webinar addresses guying options to solve problems of insufficient guy leads and space limitations on poles. Specific applications to be addressed are span guys, spread guys, and sidewalk guys.
2017 NESC Clearances from Buildings, March 9, 2021
Many accidental contacts occur near buildings, which is why this webinar addresses the clearances required by NESC Table 234-1 when passing by a building, but not attached to the building. This webinar provides a working understanding of the clearances required over or beside buildings and other structures.
NESC Grounding Requirements, April 13, 2021
The NESC provides methods and requirements for grounding distribution systems because proper grounding is an important component of safety for line workers and the public. This webinar addresses the safety goals and describes approved methods for effectively grounding the system neutral and other non-current carrying equipment. Different types of grounding electrodes are covered which provide options for achieving a well-grounded system. The rules for grounding guys and insulating guys, including secondary guys and span guys, and the equipment to be grounded are also addressed.
Connecting Residential Solar and Batteries to the Grid, May 11, 2021
More rooftop solar and commercial solar are being installed by consumers to defray their energy bills, and batteries such as the Tesla Powerwalls are gaining in popularity. The course provides a detailed review and application of IEEE Standard 1547 for interconnection of inverter-based systems including solar and batteries. The webinar will focus on residential scale interconnection.
Product Review of Three-Phase Pad-Mounted Switchgear, June 15, 2021
There are many different manufacturers of pad-mounted switchgear, so this webinar will explore the characteristics of different devices with summaries of capabilities and applications. This will include insulating mediums (air, oil, SF6, solid dielectric), overcurrent protections, automation, and mounting methods.
How to Place Capacitors on a Distribution System, July 13, 2021
This webinar will
discuss placing distribution capacitors to maintain an efficiently operating
distribution system. Issues addressed will include defining var flows and their
impact on the distribution system; placement of capacitors and that it must
consider daily and seasonal variability of var flows; and strategies for
placement of capacitors, including voltage support, loss reduction, and
NESC Clearance on Poles, August 10, 2021
Separation and spacing requirements for conductors on the pole are provided throughout the NESC. Often this spacing is reflected in the construction specifications. The webinar will explore the spacing requirements and how those requirements affect the design, as well as the requirements of the NESC as it relates to safe clearances for communication workers and supply utility workers.
Application and Coordination of Overhead Fees, September 14, 2021
Fuses are the
most common overcurrent devices used on overhead power systems. This webinar
will discuss the characteristics and application limitations of expulsion
fuses; the concept of fuse savings and the coordination requirements for
upstream reclosers; the methods used for sizing fuses to protect overhead taps;
and methods used to coordinate multiple fuses in services.
Multi-Circuit Design Considerations, October 12, 2021
Designing a double circuit line is similar to designing a single circuit with an added degree of complexity. This webinar discusses the challenges of designing a double circuit line, including large angle poles, equipment poles, circuit spacing, and guying and anchoring.
Methods for Improving Reliability, November 9, 2021
Reliability, expressed as SAIDI, SAIFI, and CAIDI, is used to help compare the reliability of a system from year to year as well as comparison to other utilities. The webinar will explain the indices (SAIDI, SAIFI, and CAIDI) and the use of outage data to develop actionable methods for improving reliability. The webinar will also discuss methods for improving reliability via several case studies.
Motor Starting, December 7, 2021
Mitigation of power quality issues due to motor starting on the power system can be one of the most difficult challenges faced by electric utility personnel. This course discusses how to prepare a motor starting analysis for various types of motor starters. The impact of the various motor starters on the starting current and starting torque will also be discussed as well as mitigation techniques.
These webinars will be recorded. Registrants will be emailed a copy of the recording after the webinar.
