Abstract
The life of power transformers faces a growing threat from space charge in oil-paper insulation. Many works explored space charge behavior in this system. This review examined hypotheses and measurement techniques. Findings from earlier studies helped understand space charge production and its impact on the oil-paper surface. The review discussed internal and external factors influencing space charge behavior. Experimental procedures offer technological advantages. Despite some understanding, current methodologies can't predict space charge consequences accurately. The review suggests developing a unique approach to comprehend space charge behavior in oil-paper insulation, safeguarding power transformer functions.
