Measurements of process parameters have historically been accomplished by the analog panel meter (APM). Since 1819, when Oersted proved the existence of current in a wire by using a compass needle positioned next to a conductor, APMs have been the main indicator for all kinds of monitoring. (more...)
Average loading on transformers is increasing as utilities strive for higher asset utilization. Higher loads mean hotter operation and the need for improved thermal management. Intelligent transformer monitors, such as the Weschler Transformer Advantage, provide users with reliable thermal data and flexible cooling control. (more...)
