The major aim of the study was to develop and validate volunteer motivations scale for international sporting events (VMS-ISE). A growing body literature suggested that vary with nature activity context. Although numerous studies have identified various motivational factors on human services in general, little has attempted conduct a at mega events. In study, using 2002 FIFA World Cup sample, exploratory factor confirmatory analyses revealed six-factor solution: expression values,...
The mechanical condition of a circuit breaker, i.e., whether the unit is in normal or abnormal condition, has been evaluated using noninvasive diagnostics, together with signal processing and decision-making techniques. Test procedures involved obtaining vibration signals from transducers placed along external surfaces (and, under certain conditions, within interior of) breaker. Using method, quantitative assessment breaker can be carried out for any operating condition. Tests oil sulfur...
The authors evaluate the technical and economic feasibility for active filtering of DC-side voltage harmonics AC-side current produced by a HVDC (high direct current) converter. following designs filter concepts are compared with existing passive filters used at Dickinson terminal CU transmission line project: consisting capacitor coupled injection source to neutralize 12th, 24th, 36th actively designed provide same fundamental frequency-reactive VARs as filters. Controlled currents injected...
Frequency-dependent node-to-node impedance function (NIF) models of power system equipment based on systematic broad frequency range (50 Hz to 1 MHz) external driving point measurements are described. Such needed calculate and predict the radio electromagnetic (EM) noise produced by valve ignition a converter station. The application transformer frequency-domain NIF model related HVDC station EM calculations is demonstrated. Calculated performance data compared with field measurements.< <ETX...
Differing theoretical and methodological views working-group needs have spawned a wide diversity in the content, layout internal structure of terminological entries database environments, which turn complicates standardization data interchange. Major criticisms lodged against element list provided ISO 6156 (MATER) prompted authors to conduct an empirical examination over thirty existing databases ascertain elements are truly used practice (as opposed those espoused or rejected theory). Their...
The authors describe and summarize the results of impedance measurements 12 converter transformers nonconverter in 50 Hz to 1 MHz frequency range. Impedance characteristics associated with various parameters are discussed. Studies transformer winding first resonant frequencies prediction equations presented. Many conditions represented: single three-phase transformers, different core designs, high voltage low windings, terminations. From measured driving point impedance, it can be clearly...
Noninvasive diagnostics, involving short-time spectra, energy, and automatic timing techniques, have been applied to assess the mechanical condition of oil puffer circuit breakers determine events occurring during operation. A portable instrument that employs these techniques has developed tested at various utilities. The capabilities this results field trials are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Radiofrequency (RF) quantities in and around an HVDC converter station were measured the 0.1 to 5 MHz frequency range provide baseline data for formulation of a means predict RF performance such stations. Special records taken at selected points traverses station. The voltages buses ground-level electric field strength magnetic flux density measurements conducted. To obtain maximum amount information about pole when it is considered as source, swept (broadband) prime analysis performance....
High-voltage direct-current (HVDC) converter stations generate radio frequency (RF) electromagnetic (EM) noise due to valve firing. The propagates into the AC and DC switchyards along their corresponding transmission lines. This can affect performance of adjacent communication, control, computer equipment, it interfere with carrier system operation. Therefore, is important measure, predict, mitigate EM interference. Measurements on equipment are necessary for purpose determining these...
Noninvasive diagnostics, involving short-time spectra, energy, and automatic timing techniques, were used to assess the mechanical condition of oil puffer circuit breakers determine events occurring during operation. Analysis vibration signatures leads (1) characterization a breaker through single index, resolution ratio, (2) algorithms. The accuracy algorithms permits both detection shifts in associated with changes unit. Application these methods several SF/sub 6/ is described. Results are...
This article discusses translation-oriented terminology over a time frame that is more or less congruent with META’s life span. Against the backdrop of place in shaping professional issues translation, we initially describe some stages process by which has acquired institutional identity translator training programmes and constituted its knowledge base. We then suggest framework seeks to show how theory construction contributed better understanding technical texts their translation. A final...
