3288: Analytics for Maintenance of Overhead Transmission Lines

OTE 3288 – Analytics for Maintenance of Overhead Transmission Lines focuses on developing an analytical framework for data analytics to optimize overhead transmission line performance.This project further developed primary and secondary data analytics from three previous CEATI efforts to develop an easily implementable real-world framework to optimize overhead transmission line maintenance and repair-versus-replace decisions.The project developed a data analytic framework to answer questions, su

3220: Use of Non-contact Laser-Ultrasonic Method to Detect Cracks in the Shell of Porcelain Insulators Phase I: Feasibility Study - Laboratory Testing and Development

The objective of this project was to use non-contact laser-ultrasonics to excite acoustic vibrations in insulators using a generation laser and to measure the vibrations using an optical interferometer. Various inspection techniques were tested on a number of cracked and uncracked porcelain insulators. Only samples with large (a few centimeters long), visible cracks in the insulator shell were available for testing. The non-contact laser-ultrasonic inspection method tested, employing pulse laser

50108: Detection Of Unintentional Islanding On Distribution Systems

There are a number of challenges associated with the increased penetration of DistributedGeneration (DG) in distribution circuits – one of them is the danger associated with creatingunintentional islands. Islanding refers to the condition in which the DG is isolated on a portion ofthe electric power system and operates as an "island" that is separated from the area electric powersystem. Islanding is often referred to as “loss-of-mains.” DG must have the capability to reliablyde

0382: CPF: Criteria for the Identification and Selection of Environmentally Acceptable (EA) Lubricants

The adoption of environmentally acceptable (EA) lubricants requires both industrial and regulatory support. To obtain this support, EA lubricants must meet critical environmental and performance specifications. However, the standard specifications currently listed by lubricant formulators do not provide sufficient clarity that these environmental and performance requirements are being met. For this study, methods for identifying high quality environmentally acceptable (EA) lubricants were assess

5153: Voltage Depression Caused by DG Anti-Islanding Protection

This project investigates a new power quality concern that may emerge as more distributedgenerators are added to a feeder. The problem is associated with the DG anti-islanding protection.This protection requirement has an unintended consequence. When an electrical island isreconnected to the supplying feeder after the operation of the anti-islanding protection, its loads areenergized immediately. However, the DGs are no longer present since they cannot be reconnectedimmediately. This creates a l

7069: Analysis of Attribution of Energy Savings at the End of Persistence

Energy efficiency measures installed as part of a demand-side management (DSM) program result in energy savings over the life of the measure. Accurate estimates of lifetime energy savings are important to administrators to ensure that all benefits of the program are attributed for cost-effective analysis and energy planning. Typically, no energy savings are attributed to a utility program from an energy efficiency measure at the end of its Expected Useful Life (EUL). However, there may be circum

3229: Satellite Technology Applications for Monitoring Electric Utility T&D Assets and Rights-of-Way

A review of the potential applications of Earth observation satellites was carried out for the benefit of the electric utility industry to determine the feasibility of using the technology in its operations. Focusing on nine specific activities that usually make use of aerial photography and other forms of detailed geospatial data/information, the study provides examples of potential applications and assesses their likelihood of implementation and the forecasted barriers to their introduction.

5075D: Worker Protection on De-Energized Underground System- Phase IV

This project is a continuation of previous studies on the safety conditions for personnel working on de-energized overhead distribution lines. More specifically, this study extends the previous works to underground systems with voltage levels of up to 35 kV. The focus is on protecting personnel working on de-energized cables from shock hazards due to accidental energization and electromagnetic coupling of nearby energized cables. In principle, the same worker protection methods currently being u

3411-2: Transmission Underground Cable Reference Manual - Chapter 2: Installation and Inspection

In most North American cities, underground power transmission depends on highly engineered cable systems capable of functioning reliably under extreme conditions during a lifetime of 50 or more years. The components that make up these cable systems are manufactured in specialized factories from highly refined materials, using precision equipment and subjected to rigorous quality control measures. Before shipment, all cables and accessories are tested to verify compliance with industry standards

3733: Best Practices in Copper Theft Mitigation

Copper is a vital component for electrical power systems as utilities are heavily reliant on copper conductors given its impressive ductility, malleability, anti-corrosive, and conductive characteristics. However, the high scrap metal value of copper makes utility facilities and assets a likable target for copper thieves. Copper theft from electricity infrastructure not only threatens the reliability of the electric grid, significantly costing the utilities millions of dollars in repairing and f
