Video: Program keeps poles healthy, reliable

Mark Madler and his crew were thankful for the picture-perfect day in which they were working.

“We could do these all day,” said Cody Woodworth, OPPD line technician. “We don’t get them like this too often.”

Woodworth was referring to the weather, yes, but also to the work he, Madler and fellow line tech Jason Cavanaugh were doing. The trio were replacing poles along Fort Crook Road in Bellevue.

Healthy system

A pole there had been “red tagged” by an OPPD contractor who inspects the approximately 240,000 distribution poles that make up a portion of the OPPD electricity grid. The process is part of OPPD’s Ground Line Inspection and Treatment (GLIT) power pole replacement program.

To ensure the grid’s reliability, OPPD goes to great lengths to make sure the distribution and transmission systems are healthy.

The most visible method are the helicopter transmission inspection flights done twice a year over less populated areas. During the flights, line maintenance techs like Gary Wohlman and Mark Gorseth fly near over 1,300 miles of transmission line as part of the program.

But while the flights obviously cover a lot of ground, Wohlman and his co-workers still spend plenty of time out on the road and down on the ground. It’s there that they get an up-close look at the poles as part of an overall asset management and maintenance program and reliability based philosophy.

OPPD follows a set schedule for pole inspections, typically checking 10 percent of the poles each year. The power pole replacement program began in the early 2000s and inspections run on a 10-year cycle.

Changes lead to improvements

Thanks to changes in the process, that backlog is becoming far more manageable. Line maintenance techs Wohlman and Gorseth work with iPads in the field to gather information on the rejected poles.

On this day, Wohlman had a series of poles to check north of Blair. He pulled up the “red tags” on his screen and his iPad’s GPS led him right to the county road where he could easily see a pole with a red tag.

“We still use the actual tags,” Wohlman said. “We do that so our linemen can see them and know their condition at a glance.”

He was able to bring up that pole and a few others in the area on the iPad rather than spreading out a large map. Techs and crews used to spread out those maps on the dashboards of their work trucks before computerization. That’s just one example of how much easier the inspections and replacements are now.

Hutchinson said that through updated technology and processes, far fewer hands are touching the work.

“We’ve bridged the gap between the inspection process and the resource management process,” Hutchinson said. “When we began, we couldn’t get all of the work done, but now we’ve standardized the work and have given them the tools to do it.”

The process change frees time for the various workers involved. When including time spent by crews, engineers and paper resources used, OPPD saves nearly $70,000 each year, Hutchinson said.

Eyes on the ground

Wohlman gets out of his truck and snaps pictures of the pole with the iPad. He attaches the photos to the work order he fills out from his screen. He inspects the pole and can create the work order from his truck. The work orders identify the materials needed and automatically calculate the cost and number of hours needed to do the work.

A smaller number of poles are considered “priority poles.” The program designates these for replacement right away.

Hutchinson said the poles suffer exterior damage from weather or car crashes, but the majority need replacement after rotting from the inside out. Poles can start to degrade faster in years 13 and 14. That’s when the treatment in the pole deteriorates and needs renewed through the GLIT program. Inspectors take small core samples – about the size of a cork – out of the pole to test its interior health.

Keeping workers safe

The work is not only important for the health of the electric grid. It also makes work safer for those who have to climb the poles.

In 1948, 49-year-old lineman Arthur Pakiser died after falling 35 feet from a pole that broke off near its base in Herman, Neb. Another worker, Bert Christensen was also injured in the fall.

Personnel patrol the poles from South Sioux City in the north to Rulo, Neb., in the south. Once crews complete a work order, it becomes “on the shelf work.” This means it is done between bigger projects, whenever it can be fit in.

Some of them are pretty simple fixes – like the one along Fort Crook Road – but others are more complicated.
