0415: CPF: Water Management Research Initiatives

Water resources are the fuel for hydroelectric production, and the efficient and effective management of these resources is a fundamental part of the hydropower business. Significant time and effort has been expended by utilities to understand the science, gather and analyse data, and develop or run models to optimize the resource. This work is sometimes undertaken by larger utilities or contracted out to consultants, research institutions and universities. There are also a number of tools and p

3268: CPF: Using Inspection Data to Establish Appropriate Inspection Cycles for Transmission Lines

This project presents a model and tool that permit an asset manager to vary the inspection interval via the use of a mathematical model based on the age of the asset, the criticality of the asset, the number of actionable component conditions identified in the field, the respective risk associated with each of the field conditions, and the remedial cost of the condition in the field. The model can be applied to a group of assets upon conclusion of each inspection cycle to adjust (i.e., lower or

3226: Transmission Line Structures - Recoating While Energized

The expected increase in live-line work approaches and the extremely important safety considerations involved in planning and executing work on or near energized circuits have contributed to a need to document and collate technologies, methods and approaches for recoating transmission structures without having to schedule a line outage. This study examines methods and procedures for recoating/repainting transmission line support structures while energized with an emphasis on safety which have b

7059: Review of Packaged Roof Top Equipment (RTU) Upgrades for DSM Utility Programs

Packaged heating and cooling rooftop units (RTUs) are widely utilized for space conditioning low-rise buildings and are major energy consumers in the commercial and institutional sectors. Advances in both cooling and heating technologies create the need for a better understanding of RTU energy savings potential. The objective of this study is to complete a technical and market assessment of current and emerging RTU advanced technologies to determine gas and electricity savings potential compared

3259: Guide for Condition Assessment of Lightning Arresters Installed on Transmission Lines

The transmission line arrester assessment guide has been written for transmission line personnel, from the novice to the most experienced journeyman. In order to make the guide as useful as possible, the first two chapters are dedicated to the basics of arresters. Terminology is covered in detail for both IEC and IEEE related users. A number of pages are dedicated to the fundamentals of arresters in general, as well as the proper means for selecting transmission line arresters. Following the tut

7053: Efficiency Testing of Switched Reluctance and AC Permanent Magnet Motors

Many industrial processes require precise and accurate control over system parameters such as flow, pressure, temperature, process speed, etc. The use of a variable frequency drive (VFD) to match the motor driven equipment’s speed and torque to the requirements of the process load can result in large energy savings, particularly in variable torque or centrifugal loads. It is estimated that 30 % of industrial motor systems may benefit from the application of a VFD to control motor speed and

33109: Numerical Simulation of Transmission Line Vibration Caused by Ice Shedding

The structural design of overhead lines accounts for extreme climatological events, including wind and ice loads, properly combined to provide adequate reliability of components. Apart from direct climatological loads (transverse and vertical), the line is also exposed to longitudinal loads arising from differential ice loads. These arise from ice shedding, a phenomenon that occurs when ice sheds and creates unbalanced longitudinal loads on adjacent structures. This work presents reviews of lite
