Lightning Strike Mitigation Program

In Iowa unexpected weather happens quickly. Many power outages are the result of lighting strikes during severe storms.

In order to reduce potential outages due to lightning, Linn County REC has a lightning outage mitigation program in place. Our goal for the lightning outage mitigation program is to provide a method of increasing system reliability by reducing lightning-caused outages. As a part of this program, Linn County REC installs integrated lightning arrestors on all of its new overhead transformers. Arrestors are an over voltage device that lessens the effect of a lighting strike by diverting some of the strike energy to the ground and bringing the line back to a normal operating level.

In addition to our transformers, all underground wires from overhead lines have arrestors installed. Substations are designed with numerous lightning arrestors in place to protect all facets of the substation facility.
