Measurement of River Discharge
Journal AWWA, 1925of usefulness grew until today they assist in the solution of problems that affect every citizen. The number of measuring stations in operation has grown from a few in the early 90's to nearly 1700 this year. During the fiscal year of 1924 there were made approximately 12,000 regular and miscellaneous discharge measurements. These statements refer only

Measuring the endurance of films in partial discharges
IEEE Transactions on Electrical Insulation, 1993A new test assembly for measuring the endurance of polymeric and ceramic films under the action of partial discharges (PDs) is presented. If experiments are performed under controlled ambient conditions (i.e., relative humidity), the test procedure gives times to breakdown which show low scatter. The effects of different test conditions on the times to

Abstract With a continuous global increase in flood frequency and intensity, there is an immediate need for new science-based solutions for flood mitigation, resilience, and adaptation that can be quickly deployed in any flood-prone area. An integral part of these solutions is the availability of river discharge measurements delivered

Measuring the instability of AC arc discharges
Microprocessors and Microsystems, 1981Abstract A digital approach using a microprocessor has been developed to give accurate values for AC arc discharge instabilities. This case study is based on theoretically interpreting the instability of arcs in terms of an instability factor related to the deviation of instantaneous values of arc voltages from a predetermined average value. A simple

Discharge detection and measurements
Proceedings of the Institution of Electrical Engineers, 1965Discharge measurements provide a sensitive, nondestructive means of detecting minute defects in insulation. The successful application of discharge-detection techniques depends on an appreciation of the following: the conditions in which discharges occur, the factors which affect the discharge magnitude and recurrence frequency, and the various ...

Power Measurements of Spark Discharge Experiments
Origins of life and evolution of the biosphere, 1998An accurate and precise knowledge of the amount of energy introduced into prebiotic discharge experiments is important to understand the relative roles of different energy sources in the synthesis of organic compounds in the primitive Earth's atmosphere and other planetary atmospheres.

Probe measurements in anisotropic discharges
Journal of Applied Physics, 2003A current–voltage characteristic of one-side planar and cylindrical probes was considered for the use in the determination of plasma parameters when the electron velocity distribution functions (EVDFs) were significantly anisotropic. The EVDFs, space potential, and rates of inelastic process in pulse modulated and stratified discharges were obtained ...

The discharge of a sewer has to be determined often over a short period only. This can serve as design basis, and an accurate discharge measurement is required only later. In this chapter, the so-called mobile discharge measurement for rectangular, trapezoidal and circular profiles is introduced.

On line measurement of partial discharges
2000 Annual Report Conference on Electrical Insulation and Dielectric Phenomena (Cat. No.00CH37132), 2002On line measurement of partial discharges of equipment while in service has a great deal of potential in saving equipment down time in gas insulated substations (GIS) and gas insulated transmission lines (GITL). To address this aspect of partial discharge measurement there is scope for considerable progress particularly in the area of cables already is

Discharge measurement structures
2017This chapter introduces calculation procedures for discharge measurement structures. It focuses on a rational expression for discharge in terms of typical flow quantities and the geometry of the structure. The chapter presents the general one-dimensional flow equations, and a demonstration that critical flow can occur if either the cross-sectional area
