50141: Inspection Techniques for In-Service Indoor and Outdoor Distribution Terminations

This project provides a comprehensive summary of best-practice inspection techniques for in-service indoor and outdoor distribution cable terminations. The project covers both pre-molded terminations and heat shrink and cold shrink terminations, air terminations, and elbow terminations.This guide includes a review of the structure of terminations as well as modes of failure to identify how incipient failure could be predicted and avoided. The report serves as a guide to help avoid, identify, and

3285: Asset Management System for Transmission Lines

In this project, a review was conducted to compare different Asset Performance Management (APM) platforms currently available in the market. The main objective of this project was to determine functions and features that are critical for asset management of transmission lines, examine feasibility of meeting these features, search for commercially available platforms that meet the defined requirements, and set up guidelines on selection of appropriate APMs based on each utility’s specific r

3263: Conditioned Based Asset Management of Overhead Line Infrastructure-A Probabilistic Framework

Rigorous maintenance practices for overhead lines not only extend an asset’s life, but can also detect damage conditions early to avoid a premature failure, thus avoiding forced outages. Traditional time-based maintenance practices collect inspection data at a fixed time interval and execute maintenance decisions based on the processing of asset condition data, which are primarily deterministic.This report uses a stochastic model (Markov chain model) to apply asset condition data; this mod

0394: Hydro Generator Stator Winding Flammability Study

The purpose of this investigation was to determine if generator stator bars/coils with Class F insulation have self-extinguishing behavior. Specimens included samples prepared from both VPI and resin rich manufacturing processes with either a taped or painted stress control treatments. Specimens were selected from new, spare, and used specimens subjected to TCT/VET, as well as specimens from a generator removed from service. Testing examined the effects from an electrical arc, an ejected plasma

3247: CPF: Transmission Line Maintenance Benchmarking

Numerous types of inspections at various frequencies are carried out on a transmission line system. This is done for two main reasons: to identify defective components that need immediate attention as well as those that can be corrected over time under a planned program, and to identify issues that require follow-up to determine the full extent of a problem. During inspections, condition data is also collected to support maintenance and capital replacement planning. These inspection activities,

0430: CPF: Roadmap for Applied Statistical Analysis Techniques for Hydro Generation and Runoff

Hydropower operators are busy with day-to-day operations. They need to an actionable tool that guides them to appropriate statistical methods to process the vast amounts of data related to inflow forecasts and runoff determination. CEATI previously published two reports (CEATI Report No. T132700-0425 Review of Data Screening Methods for Discharge/Inflow Time Series and CEATI Report No. T152700-0426 Applied Statistical Analysis Techniques for Hydro Generation and Runoff) that provide operators wi
