For Immediate Release
Newark, DE -Delmarva Power reminds customers that while adequate supplies of power are available, it is important to conserve energy to help ensure the reliability of the electric delivery system during the extreme heat and high humidity forecast for the next few days.
As customers try to keep cool with air conditioning, increased demand for electricity affects distribution lines. Increased power flowing through the lines causes them to heat up and expand or sag. In some cases the sag is great enough that the line comes into contact with tree branches growing near the line, causing a short circuit or outage. The high current flow can cause heating and stretching of cables, switches and other equipment, resulting in an outage.
Electricity loads in combination with high ambient temperatures can also cause transformers to heat up to very high temperatures. Such conditions can permanently damage equipment.
