Bulk system reliability-measurement and indices

IEEE Transactions on Power Systems, 1989
Methods and indices are presented for measuring the actual bulk power system reliability of individual utilities. Categories of unreliability events are identified for measurement, and locations in the bulk system where measurements can be made are suggested. Data requirements and indices calculations are discussed. The proposed measurement system uses

Principles of Defining Reliable Change Indices

Journal of Clinical and Experimental Neuropsychology, 2000
In this article, several salient measures for determining reliable change are scrutinized. The classic null hypothesis method is compared with more recent procedures based on interval estimation of the true change, including Kelley's formula. The latter category of methods are shown to entail serious drawbacks. If Kelley's formula is expanded to a null

Investigating Reliabilities of Intraindividual Variability Indicators

Multivariate Behavioral Research, 2012
Reliabilities of the two most widely used intraindividual variability indicators, ISD (2) and ISD, are derived analytically. Both are functions of the sizes of the first and second moments of true intraindividual variability, the size of the measurement error variance, and the number of assessments within a burst. For comparison, the reliability of the

Fault indicators effects on distribution reliability indices

18th International Conference and Exhibition on Electricity Distribution (CIRED 2005), 2005
SUMMARY Reduction of failure rates and applying effective fault management can be affected in improvement of reliability indices in distribution systems. One of the ways to improving the reliability of distribution networks in fault management procedure is installing Fault Indicators (FIs) in overhead primary networks.

Reliability and Validity

International Encyclopedia of Human Geography, 2020
A person’s level of attention and motivation may vary as they repeat the same test over and over again, the difficulty of two supposedly identical tests designed for measuring the same construct may be unequal, the samples of examin-ers who mark a ...

IEEE reliability indices standards

IEEE Industry Applications Magazine, 2005
This work discusses "beta method", a statistically based methodology that classifies electric power distribution reliability data into day-to-day and MED (major event days) performance. Further the article discusses the results of the evaluation of small utility data and encourages more utilities to use this methodology to determine MEDs and submit the

NVQs. Reliable indicators of competence?

Nursing older people, 2002
Most care professionals acknowledge that training for healthcare workers should improve standards of care for clients. The current emphasis is on NVQs. Manthorpe ( 2002 ) identifies training as an important component of preventing abuse within the care setting, stressing the value of using materials linked to S/NVQ in Care for the unit Z1, titled ...
