Webinar Overviews:
February 12, 2019 Impact of New Communication Equipment on Joint Use Clearances
The use of fiber-optic lines in the supply space and the desire of telecommunication to install 5G antennas in the supply space present challenges to electric utilities. This webinar addresses the NESC requirements as they relate to safe clearances for communication workers and supply utility workers. In addition, the webinar addresses methods to use for sharing space on the pole with telecommunication companies.
March 5, 2019 Changes in Arc Flash Calculations
IEEE Standard 1584 was updated in late 2018 and significant changes were made that could change the PPE used by electric utilities. These changes include elimination of the exception for transformers below 125 kVA, and elimination of the 85-percent rule. Further, the calculation now includes more shape factors for arcs that are considered to be enclosed in switchgear or similar enclosures. The new calculations are more accurate, but present challenges for electric utilities. This webinar addresses the changes and the new calculation methods.
April 16, 2019 Underground Distribution Design
Designing underground distribution differs from designing overhead distribution in terms of resiliency of the system. This webinar addresses common underground design criteria such as methods for design in underground subdivisions and commercial developments, routing of cable systems, use of conduit, burial depth, and common errors in design. Single contingency outage and overcurrent protection scheme will be addressed along with limiting factors of system components.
May 14, 2019 Specifying and Placing Lightning Arresters
Lightning can cause 20 percent of the outages on overhead power lines. This webinar discusses the type of arresters currently on the market for distribution lines. In addition, the presentation discusses the common basic impulse insulation level (BIL) with emphasis on a new method to prevent flashovers referred to as critical impulse flashover voltage (CF0). When combined, equipment BILs are 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.
June 25, 2019 Resource Planning for Distributed Energy Resources (DER)
Distributed energy resources (DER) are changing the landscape for distribution engineers in terms of planning and designing of their systems. This webinar addresses the positive and negative impacts to the grid from DER. In addition, how to plan for future system growth and resiliency with DER added to the system will be discussed.
July 16, 2019 Single-Phase Metering
This webinar addresses the fundamentals of single-phase metering including meter bases and connectivity of the single-phase meters. AMI metering has changed the landscape on single-phase metering so the presentation will address new data being collected, new controls at the meter, and alarms. Specifically, what do the alarms mean and how to address alarms such as high voltage, hot socket, and low voltage. Further, the use of demand reads, ping of the meters, and load side voltage tests will be addressed.
August 13, 2019 Three-Phase Metering
Metering of three-phase services is complex and often represents a larger percentage of utility income compared to single-phase loads. Meter Forms 8/9 and 15/16 will be addressed, including methods for sizing current transformers and potential transformers. Common wiring methods and common errors will also be discussed.
September 10, 2019 Battery Energy Storage Systems
Utility-scale batteries are beginning to make an impact on distribution systems to the point that some utilities are providing assistance to consumers who install batteries behind the meter. This webinar provides a fundamental understanding of battery energy storage systems. Further, the webinar discusses the application of battery storage both on the utility system as well as on the consumer side of the metering.
October 8, 2019 Wood Poles - Standards and Design
Wood poles have been used in the electric utility industry since its inception. There are standards for wood poles (ANSI 05.1), and the NESC provides loading and strength requirements of poles. This webinar addresses limitations set forth in the standards; NESC loading requirements such as ice, wind, joint-use attachments, and vertical loads; and the need for strength reduction factors for wood poles.
November 12, 2019 Application of Voltage Regulators
Voltage regulators are needed on all distribution systems and serve an important role in maintaining quality service to customers. This webinar will address the fundamentals of how voltage regulators operate. In addition, the presentation will cover application of the voltage regulators including placement, how to coordinate cascading regulators, and the use of line drop compensation.
