Specifying and Placing Lightning Arresters, January 11, 2022

Did you know that lightning can cause 20% of the outages on overhead power lines? Therefore, in this webinar you will review the types of arresters currently on the market for distribution lines. In addition, you will also learn about common basic impulse insulation level (BIL) with emphasis on a new method to prevent flashovers referred to as critical impulse flashover voltage (CFO); however, the combined BIL of equipment is not additive as once thought. The CFO technique for overvoltage protection will be discussed with explanations for adequately protecting overhead lines based on ground flash density, shielding, and earth resistivity.

Overhead to Underground Conversions, February 8, 2022

Trends are emerging where existing overhead distribution facilities are being converted to underground; this could be streetscaping or could be part of a reliability/resiliency program. Join this webinar to discuss these trends for undergrounding, as well as the design complexity of an overhead to underground conversion. You will learn about the challenges, which can include overhead weatherheads, 120/240 volt three-phase services, loop feed designs, space limitations, easements, joint-use attachments, and other unique situations.

Aging Infrastructure - Plan of Action, March 8, 2022

The electric grid in the United States is aging and needs to be replaced to maintain high levels of system reliability. However, with negative trends in electrical demand and potentially shrinking revenue, it is becoming even more difficult to reinvest in the system infrastructure. In this webinar you will learn the methods for the evaluation of the aging components of the utility’s system, prioritization of the necessary replacements, and planning for the logistics of maintaining and replacing system components.

Advanced Car Chargers , April 12, 2022

There are essentially three levels of electric vehicle chargers: Level 1 (120 volts), Level 2 (240 volts), and Level 3 fast chargers. The advanced Level 3 fast chargers can have demands of 1 MW for just four charging stalls. The growth in EV cars and other larger vehicles, such as buses, will have a significant impact on the distribution grid. Attend this webinar to learn the three common charging dispensers, the inverters to power the dispensers, and the demand cycle when charging EV batteries.

Electric Service for the Electric Vehicle Fleet, May 10, 2022

Public and private fleet operators are switching to electric vehicles to reduce costs, cut emissions, and to lower their carbon footprint. However, depot fleet charging can have many EV vehicles connected to chargers which can spike demand on the electric grid. In this webinar you will explore EV charging strategies that help limit kW demand and optimize charging times. You will also receive information on commercial charging and energy-as-a-service models for charging fleets.

Interconnection of Battery and Solar Systems, June 14, 2022

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. In this webinar, which will focus on residential scale interconnection, you will review the application of IEEE Standard 1547 for interconnection of inverter-based systems including solar and batteries.

2023 NESC Sneak Peek, July 19, 2022

The 2023 NESC is available in August 2022 and becomes effective in January 2023. There were over 500 change proposals submitted in this code cycle: new sets of rules are expected for utility-controlled PV plants and utility batteries as well as numerous changes throughout the NESC. Attend this webinar for a quick overview of the NESC updates.

The Do's and Don'ts of Easement Acquisition, August 9, 2022

The best-designed power line is useless without land to build it on. Acquiring easements from property owners to cross over their land and possibly cut their trees may be the hardest part of distribution line staking. In this webinar you will learn tips to obtain easements and what pitfalls to avoid.

Stray Voltage and Swimming Pools , September 13, 2022

Electric utilities receive stray voltage complaints that often occur at bodies of water, such as boat docks and swimming pools. Join this webinar to discuss methods of investigation, cause analysis, and options for corrective action. You will also review the concepts of stray currents as well as common problems and possible solutions.

Understanding Microgrids , October 11, 2022

Microgrids are small power grids operating either within a larger power grid or independently, and they are increasingly becoming advantageous to customers such as college campuses, industrial complexes, and military bases. Attend this webinar to learn about the various microgrid scenarios, development of a microgrid system, and the technologies to integrate a microgrid system.

Pole Buckling Prevention, November 15, 2022

In this webinar you will learn the primary causes and effects of pole buckling, including insufficient pole class and short guy leads; the methods to design a wood pole distribution structure to prevent pole buckling; the calculations and variables involved to perform a structural analysis; the variables necessary to perform the structural analysis; and how to determine the appropriate values for those variables.

Strength of Pole Top Assemblies, December 13, 2022

When designing a distribution line, it is necessary to select the proper pole top assembly for each pole, including crossarms (wood and fiberglass), pins, and insulators (polymer and ceramic), because the attachment methods for these components affects their strength to support maximum conductor tensions and transverse loading from ice and wind. Your focus will be on RUS assemblies, but the methods provided can be used for many unique pole top assemblies.
