Momentary power interruptions, often described as lights “flickering” or “blinking” very briefly can last from less than a second to just a few seconds. Even though the interruption is very brief, these types of interruptions can be annoying because they can affect some electronic devices and appliances in homes and businesses.
Momentary power interruptions can occur at any time, even on sunny days, and they can be caused by many factors and interferences, including:
Most distribution power lines are protected by special devices called breakers and reclosers. These devices are able to detect line interferences and shut off the flow of power to that section of the power line for a split second. This design often allows any interference the ability to clear the power line on its’ own.
For example, if a tree branch makes contact with our power lines, the system detects this interference and shuts off electricity to that section of the line for a moment. If the contact is eliminated, either because the tree limb falls or snaps back into place away from the line, the problem is resolved without an extended outage. This is how momentary power outages can help to prevent damages and extended outages.
Good design and maintenance of electrical systems are essential. IPL constantly monitors and analyzes momentary outages to identify opportunities for improvements that will help to maintain safe and reliable service for our customers. IPL conducts a variety of routine maintenance programs, such as tree trimming along overhead distribution lines which can reduce interferences by decreasing occurrences of fallen branches. We conduct routine line patrols and we even add animal safeguard devices to discourage animal and bird interferences.
