MidAmerican Energy adds fault indicators on grid lines


US based MidAmerican Energy is adding hundreds of smart devices to electric lines to help restore service more quickly if an outage occurs.

The project will help the utility to easily and quickly locate the source of a power outage without service crews being deployed to physically inspect electric lines and equipment.

The fault indicators will remotely transmit power outage data to the utility’s control room if they detect a service interruption.

“This smart grid technology helps us identify and isolate outages more quickly so we can restore service faster to minimise the impact to our customers, and supports our ongoing efforts to increase system reliability for our customers,” Jim Dougherty, MidAmerican Energy vice president of electric delivery, said.

The development helps reduce maintenance costs and the utility’s carbon fooprint.

Since 2017, MidAmerican Energy has installed more than 200 sensors in Sioux City, Council Bluffs, Fort Dodge, Des Moines, Waterloo, Iowa City and the Quad Cities, and in rural areas throughout its service territory.

The announced project includes the installation of an additional 150 units.

MidAmerican Energy supplies gas to 770,000 electric customers and 751,000 natural gas customers in Iowa, Illinois, Nebraska and South Dakota.
