0234: Using Maturity Matrices to Evaluate Dam Safety Programs

Maturity matrices are a powerful tool to evaluate how well-developed a process or program is. The maturity matrices described in this manual have been developed for owners to assess the effectiveness of a dam safety program against industry practice.In this maturity matrix, the current state of development (or maturity) of a dam safety program can be evaluated. If required, improvements to the program can be subsequently developed, prioritized & planned and then the process can be repeated at a

3406A: Acceptable Vibration Limits and Forces in the Vicinity of Underground Cables, Phase I

The purpose of this project was to develop a methodology to determine acceptable vibration levels when performing construction work in close proximity to various types of underground transmission cables. In addition to vibrations near construction sites, the influence of traffic vibrations on cables and vibrations in cables installed on steep slopes were also investigated. In this first phase of the project, a literature search was undertaken. This report lists and summarizes the published infor

0213D: People, Technology, and Organization (PTO) Application to Emergency Preparedness Plans (EPP)

The overall goal of this project is to provide recommendations for the design of a “toolkit” which dam owners can use in order to apply PTO to evaluate gaps in the commonly accepted practice for dam safety emergency preparedness. In addition to the development of the toolkit addressing an integrated approach to emergency preparedness, this will also deliver on an improved understanding and training for dam owners in applying PTO to their specific Emergency Preparedness Plan processes

0364: CPF: Hydraulic Phenomena that Occur in Operating Hydraulic Turbines

Undesirable levels of pressure pulsation, power swings, vibration, and/or noise may occur duringoperation of hydraulic turbines, storage pumps, and related equipment. Sometimes other parts of theplants, such as the generator, penstock, or the building structure, are also affected. In most cases,some hydraulic phenomenon is the root cause. Several quite different kinds of phenomena arepossible. This fact often inhibits proper diagnosis and, as a consequence, successful countermeasures. This repor

30131: Asset Intelligence for Root Cause Failure Analysis

This report is a comprehensive guide for performing a structured Equipment Root Cause Failure Analysis (ERCFA), with specific emphasis on substation equipment. It provides guidance on performing an ERCFA, including the tools to use, and how and when to use them. It includes checklists for the data sources needed for major substation equipment categories at the start of an ERCFA investigation. It also provides as an example an actual ERCFA that was performed for a loss of all DC control power eve

3357: Guide to Identify and Rank Critical Facilities

Transmission lines and power transformers at transmission substations represent a major portion of bulk transmission systems. and these assets must perform well in order to achieve a high level of reliability for the bulk power system. Such high performance can be achieved if there are no budget restrictions. In many cases, budget constraints have been imposed, and the owner of the system has to set priorities with regard to the work that needs to be done on these transmission components. Such w

3068: Power Circuit Breaker Reference Document

High voltage power circuit breakers installed on the power system are required to perform a wide range of switching and protective duties. These duties range from interrupting high fault currents of up to 80 kA down to the relatively low currents associated with switching loads, transmission lines and cables, and shunt capacitor and reactor banks. A very limited number of high voltage circuit breakers having exceptionally high short circuit ratings of 87.5 kA and 100 kA have been installed

3074: Contingency Planning Criteria: On-Site or Off-Site Spare Equipment, Components, and Mobile Equipment

The objective of this project was to identify the criteria utilities use when developing their strategies for the selection and management of spare equipment and spare components for major equipment. As part of the project, a utility survey and literature search were undertaken to gather information on this topic. The survey also included the strategy applied when preparing for emergency restoration of failed equipment such as transformers and circuit breakers and how the use of redundancy desig
