WebEffective Partial Discharge (PD) localization can detect the insulation problems of the power equipment in a substation and improve the reliability of power systems. Typical Ultra-High Frequency (UHF) PD localization methods are mainly based on time difference information, which need a high sampling rate system. This paper proposes a novel PD localization … WebTo calculate discharge, multiply the area of water in a channel cross section by the average velocity of water in that cross section. In short: discharge = area X velocity The simplest way to measure discharge is … WebCurrent-meter measurements from bridges: Bridges are often used for making discharge measurements of streams that cannot be waded. Such measurements are often satisfactory, but cableway sections are usually superior. Either the upstream or downstream side of the bridge can be used for making a discharge measurement. cindy chin realty
