Effective Measures of ''Effective Discharge''

World Environmental and Water Resources Congress 2008, 2008
Abstract The concept of effective discharge, Qe, was introduced by Wolman and Miller (1960) as that stream discharge that transports the most sediment over time. Recently, the validity of Qe as an overall descriptor of sediment transport has been questioned because of its various interpretations and methods of calculation.

The Nature of the Measurement of Partial Discharge

2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019
The measurement of partial discharges in solid insulation is predictive of the long-term performance of the insulation. That makes the measurement very important in high-voltage technology. The topic has been of interest for a long time, and has been extensively studied around the world.

Partial Discharge Measurement

2014
This chapter is devoted to the measurement of partial discharges (PD) localized in weak spots of dielectrics if subjected to high test voltages. As standards for PD measurement s have been introduced only for quality assurance tests of HV apparatus energized by power frequency AC voltages (50/60 Hz), the following treatment refers mainly to this test ...

The measurement of discharges in dielectrics

Journal of the Institution of Electrical Engineers, 1936
The importance is emphasized of being able to differentiate between an increase in the power factor of a dielectric due to gaseous ionization and an increase due to other causes. The necessity of being able to detect discharges before they have caused sufficient damage to give rise to a change in power factor is also pointed out.A description is given ...

Equipment for the Energy Measurement of Partial Discharges

IEEE Transactions on Electrical Insulation, 1983
The energy dissipated by partial discharges (PD) can be estimated from the U i Q i . It has been described a particular device able to deal with such a calculation using a correlator unit. With gas chromatography analysis a satisfactory correlation was available between the degradation products of liquid (oil) or solid (pressboard) insulation and the ...

Measuring health literate discharge practices

International Journal of Health Care Quality Assurance, 2017
PurposeHealth literate discharge practices meet patient and family health literacy needs in preparation for care transitions from hospital to home. The purpose of this paper is to measure health literate discharge practices in Ontario hospitals using a new organizational survey questionnaire tool and to perform psychometric testing of this new survey ...

A testbed for measuring battery discharge behavior

Proceedings of the seventh ACM international workshop on Wireless network testbeds, experimental evaluation and characterization, 2012
We describe a work-in-progress testbed for studying how the energy performance of protocols and applications for small wireless devices is affected by battery discharge behavior.
