Accuracy tests were performed on whole-current and transformer-operated electronic energy meters under conditions that reflected the actual adverse metering site conditions. Analysis of the test data reveals the deleterious effect of high ambient temperatures on the measurement accuracy and precision of electronic meter indications. Based on the study(More)
Now days, air conditioning systems are a must for almost every commercial and residential building to achieve comfortable indoor conditions. The increasing energy demand, and increasing oil prices and pollution levels raise the need for alternative air conditioning systems which can efficiently utilize renewable energy resources. The liquid desiccant-based(More)
The study presents the results of experimental investigation of finding out the maximum acceptable concentrations of DBDS, sulfur mercaptan, and optimal concentration of passivator for safe and prolonged operation of power transformers in the local environmental conditions of Saudi Arabia. For experimental investigation of optimal concentrations of DBDS and(More)
The study presents the results of experimental investigation of finding out the limit concentrations of DBDS and sulfur mercaptan for safe and prolonged operation of power transformers in the local environmental conditions of Saudi Arabia. For experimental investigation of limit concentrations of DBDS and sulfur mercaptan, new oil free of sulfur compounds(More)
This paper presents experimental findings of the effect of temperature on corrosive sulfur formation in transformers. To conduct the experimental study, new transformer oil was randomly selected and heated at 40, 60, 80, 120, and 150 °C temperature for 72 hours each along with copper strips wrapped with insulation paper and immersed in oil in accordance(More)
The potential increase of the connected capacity of renewable energy sources in Saudi Arabia will open the doors for more investment in energy storage especially pumped storage hydro (PSH). New PSH, particularly in areas with increased wind and solar capacity, would significantly improve system reliability while reducing the need to construct new(More)
