Approximately $4.5-million project will improve service reliability
JACKSON, Mississippi – To keep the power flowing, Entergy Mississippi has installed dozens of new devices throughout its service area in places that have experienced multiple outages.
Called reclosers, these devices are basically circuit breakers that temporarily open a line when momentary problems occur, such as a tree limb falling on a line or an animal getting into equipment. This “sectionalizing” of the power grid does three things:
helps prevent additional damage to equipment,
reduces the frequency and length of outages and
reduces the number of customers affected.
“A recloser is a lot like a circuit breaker in your house,” said Robbin Jeter, Entergy Mississippi vice president of distribution operations. “When a breaker overloads or short circuits, it cuts off electrical current to the problem line until the issue can be safely addressed. If a limb or animal brushes the line, the power comes back on automatically when that line is cleared.”
If there is a brief problem on the electrical system and it can correct itself, customers may only experience a momentary blink. However, while the reclosers can prevent or reduce some outages, they cannot restore power in the event of major damage, such as when a tree falls on a line or a car hits a utility pole.
“We used historical data to determine where reclosers would have the most impact in reducing the number of customers affected should a power outage occur,” said Jeter. “By adding equipment that isolates areas experiencing problems, overall customer power disruptions can be
