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 distribution does not always describe the behavior of the measured values, a beta-distribution is more proper for this purpose.
Keywords: Reflection, EM Field, Beta Distribution, Measurement, Measurement Uncertainty A System to Measure the Distribution of the Voltage Measures
