More than 50 percent of all fatal highway crashes occur at night, even though night time traffic volumes are only 25 percent of all traffic. Roadway lighting helps to reduce this hazard. This webinar will discuss AASHTO and IES standards for luminance and illumination. The effects of glare as well as methods for glare reduction will be presented. In addition, the standards for lens and lateral distribution patterns, standard pole spacing, and lighting layouts will be discussed.
ALL WEBINARS BEGIN AT 10:00AM CENTRAL TIME
Designing Roadway Illumination / April 14th 2020
Designing Poles near Airports / May 12th, 2020
Regardless of whether the airport is a licensed regional airport or a turf runway airport, it will need electric power. Tall poles near runways and taxi ways can present a hazard. The glide paths and obstruction free zones adjacent to the runway have specific maximum height requirements given the type of plane using the runway. This webinar will discuss the FFA requirements for glide paths and maximum height of poles. The webinar will also address hazard marking of poles near landing zones.
Designing Secondary and Services / June 9th, 2020
This webinar will address voltage drop and flicker requirements for electric services. The voltage drop through the transformer, secondary and service conductor can create a power quality problem if not designed properly. A new software tool estimating the drop voltage and flicker will be demonstrated and provided to attendees.
Load Balancing on Wye Systems / July 7th, 2020
Every winter and summer, utilities dispatch crews to change phases on taps in an effort to balance the load on the system. This webinar will explain the importance of load balance to reduce losses and to improve the overcurrent protection systems, techniques and methods will be presented as well as best practices for system load balancing.
Pole Foundations / August 11th, 2020
The strength of a distribution pole relies on the stability the of the pole foundation. This webinar will discuss various methods to improve foundation stability including pole foam, deeper setting depths, gravel backfill, and pole keys. Additionally, the discussion will include methods for estimating the stability of the soil.
Comparison of Wood and Non-Wood Crossarms / September 15th, 2020
Utility designers have more options available for support arms than ever before. This webinar will focus on the different types of support arms and materials used. The mounting techniques and braces will also be addressed. Application based pros and cons of different crossarms will be discussed to aid in selecting arms. Strength of the arm and NESC requirements will be discussed.
Conservation Potential Assessments / October 13th, 2020
On national, regional, and local levels, energy conservation, or energy efficiency, is viewed as a reliable, low risk, and high return energy resource. A conservation potential assessment (CPA) helps utilities determine where the most cost effective energy efficiency lies and where to target program efforts. The results of a CPA are often used in conjunction with Integrated Resource Plans (IRPS) to help optimize a utility’s electric supply resources. This webinar will discuss the elements of a CPA, a comparison of the CPA with supply-side resources, and the utilization with the IRP.
Reducing Animal Caused Outages / November 10th, 2020
Since animals cause many outages, it is often easy to blame an unknown outage on a squirrel. Many different products are on the market to help reduce animal caused outages and each product focuses on a certain animal and situation. This webinar will explore the logistics of animal caused outages and the theories behind the deterrent systems, Squirrels, snakes, birds, gophers, and large animals will be discussed along with the environment factors that need to be considered in the selection of deterrents, For instance, snakes often come into a substation because of nesting birds. Preventing nesting birds will reduce snake caused outages.
Storm Hardening—Best Practices / December 8th, 2020
The industry is moving from reliability to resiliency where resiliency defines how quickly a system recovers from a major event. Although storm hardening of the entire system may not be practical, focused storm hardening for key structures is both effective and economical. The webinar will present best practices used throughout the industry to harden key structures or segments of line which will aide in dater restoration of the system. The webinar will discuss best practices for different types of events (flood, wind, ice, etc.) and how these practices create cost effective means for resiliency.
