0256: Dam Safety Performance Monitoring and Data Management – Best Practices (2024 Update)

Geosyntec Consultants (Geosyntec) was selected to update the CEATI Report No. T082700-0210 "Dam Safety Performance Monitoring and Data Management – Best Practices" to help CEATI’s Dam Safety Interest Group (DSIG). The updates to the original CEATI Report were requested in the scope of work defined by CEATI, complementing the input from selected CEATI members. Hence, updates were restricted to some sections of the Report and focused on the importance of (i) visual monitoring and documentation as

3512: Electric Utility Guideline for Inventory and Asset Management of Cyber Security Assets

Utilities typically employ asset management programs and systems to manage the lifecycles of field equipment such as poles, insulators, transformers, turbines and generator components, and the like. Due to increased physical and cyber security threats to these traditional utility assets, and due to regulatory requirements, such as the NERC CIP standards, utilities have been deploying and managing increasing numbers of security assets. Specifically for cyber security, the assets are composed of a

3273: CPF: Guidelines for Transmission Line Pole and Tower Steel Capacity based on Corrosion Degradation

Steel transmission structures have been in service for more than 100 years. As they age, these structures are experiencing metal loss both above and below ground level due to corrosion. Significant questions have arisen regarding how much corrosion wastage (section loss) is acceptable before some type of remedial action is required. Assessing the remaining capacity of a structure due to corrosion wastage and the associated loss of member thickness is a complex process due to the different failur

5143B-14: Capacitor Bank Switching Transients

ABSTRACT: Utility capacitor banks are a key component for efficient distribution system design. Design considerations often include traditional power frequency issues such as voltage support, power factor correction, and released system capacity. However, future designs will also include power quality as a consideration as customer facilities continue the transition towards sensitive power electronic-based systems. The increasing dependence on sophisticated electronic controls and automated manu

50118B: Distribution System Health Indices: A Simplified Methodology

This project 50/118 developed simplified health index algorithms based on existing best practice algorithms to calculate health indices where the full set of condition parameters is not available. The algorithms were tested for sensitivity and applied to real-world failed asset data. The resulting study revealed that a “gateway” model is better suited to applying health indexing to assets with critical condition issues. Based on the “gateway” methodology, a “simplif

3117: Power System Stabilizers - Application, Practical Considerations and Guideline for Tuning

Power system stabilizers (PSSs) have been utilized in the electric power industry since the 1970's. The concept was first introduced by De Mello and Concordia in 1969, based on the fundamental concepts of damping and synchronizing torques. Although much research has been done in developing more refined methods for tuning and designing PSSs in the four decades that have followed, the fundamental theoretical basis is still the same - namely, for a PSS to be effective, it must induce significant ad
