Explanation:In recent years, summers in the Northeast, as well as in many other regions of the United States, have reached record high temperatures. These unusually high ambient temperatures have led to the overloading of power transformer coolers, resulting in the inability of the coolers to maintain the top oil temperature of the transformer at an acceptable level.
