Abstract During conducted measurements the reflection is one of the most varying components of the measurement uncertainty. For studying the distribution of voltage during cable reflections, in this paper we make a simple computational model and statistical analysis of the electric field to determine the distribution of uncertainty for the Voltage (Power) measurement. We also show, that the usually suggested U... During conducted measurements the reflection is one of the most varying components of the measurement uncertainty. For studying the distribution of voltage during cable reflections, in this paper we make a simple computational model and statistical analysis of the electric field to determine the distribution of uncertainty for the Voltage (Power) measurement. We also show, that the usually suggested U distribution does not always describe the behavior of the measured values, a beta-distribution is more proper for this purpose. Read More Read Less

Abstract We have developed a software testing tool to find the detection and classification of the power quality disturbances. The program was instituted in the Environment called as LabVIEW. We intended to do verify the performance of the developed tool to find the best software algorithm for power disturbances. During the power distribution networks, every real condition is simulated to find... We have developed a software testing tool to find the detection and classification of the power quality disturbances. The program was instituted in the Environment called as LabVIEW. We intended to do verify the performance of the developed tool to find the best software algorithm for power disturbances. During the power distribution networks, every real condition is simulated to find the standard power disturbances. We have developed the software induced generator to measure the long-term sequence. We have considered the European benchmark of the standards called as EN 50160. All the disturbances are explained and generated with specific functional segments. We have used the several control commands before the generator to find the unified and final composite complex testing sequence. Read More Read Less

Abstract Satellite positioning models need space and complex surface with well-developed infrastructure and it becomes difficult to institute in urban regions. The correct determination of the moving object’s location in many urban areas is increasing in the recent years. This condition warrants terrestrial navigation models that permit instituting in urban conditions to meet the correct measure of the position of the... Satellite positioning models need space and complex surface with well-developed infrastructure and it becomes difficult to institute in urban regions. The correct determination of the moving object’s location in many urban areas is increasing in the recent years. This condition warrants terrestrial navigation models that permit instituting in urban conditions to meet the correct measure of the position of the moving objects. We have developed a new model for finding the two-dimensional coordinates of objects by finding the delay of signal transmission. This transfer is instituted by many synchronized receiver stations.
