The current lesson to be learned is.......

Wet snow – lots and lots of wet snow ‐‐‐‐‐‐‐‐

‐‐‐‐‐‐ utilities must design for the “bad weather” cases thus added weight and size only complicates our ability to meet this requirement.

Based on other feedback I have received: Also, for high wind areas, if the surf ace area is increased, that adds to the torsional / torque loads, and poles need to be strengthe ned for that aspect as well. Safety clearance in urban areas can also be a problem for the width as well as the height. Typically, height is usua lly more of an issue.

Thanks for the info. For item 1, what you describe is exactly wh at we saw with the 1/1/2010 requirements. As for item 2 – weight – from what I understa nd, a change in material from silicon to amorphous improves efficiency but adds weight. So I don’t understand your statement that the manufacturer can control weight by changing material. At some point , I am sure that the weight would go up more with silicon but then size would also become unmanageable. Seems we have the weight problem regardless of the mate rial being used. Am I incorrect?

Hello Bruce:Thank you for your explanation... Sorry for little delay in respons e, I was traveling. I can certainly understand i ssues dealing with changing tran sformers where access is limited such as "back lot" services... hopefully these si tuations are limited to "older" systems and p erhaps are smaller part of your entire system. Now coming to Pole change -out issue... As I understand, ther e are two major considerations that could lead to pole change-out...

1. Height: If the height of the transformer increas es then that could lead to changing to "Taller" poles if the additional height creates encroachment issue... 2. Weight: If combined load imposed by "all" users exceeds pole strength.

As for 1st issue, as transformer's efficien cy increases, generally unit's "foot print" increases (tank diameter may increase) and height decreas es... The reason for this is that due to higher efficiency (lower Losses) "le ss cooling" surface is needed... As for 2nd issue, higher efficiency does results in higher weight due to additional materials... but as Wes's analysis has shown that this in crease in weight can be "minimized" if the manufacturer is willing to cha nge the core material... per his an alysis, weight increase can be limited to less than 15% for 30% reduction in losses... Hopefully, in most cases you will have that much margin... Hope this "Transformer De signer's" perspective is helpful... Thank you. Best Regards, Mahesh Sampat EMS Consulting 706-549-8155

The answer to your question will probably be a ll over the map. In reality, utilities are governed by the pole loading standards as set forth in the NESC. WE build our system to meet wind or ice loading requirements. The area of the Country we are in determines how much loading we can p ut on a pole and still met the standards. Company practices including third part attachments and storm hardening requirements will also affect when a pole needs to be changed. Essentially anytime a change is made on the pole (either a cha nge in equipment or an addition of equipment) the pole loading is checked to make sure it does not exceed the Code requirements. Thus, changing a transformer with a heavier transfor mer will trigger a revi ew and possibly a pole change-out.

Because we were purchasing transformers on a TOC basis (A/B factors), the 1-1-2010 DOE requirements had minimum effect on the size of our single ratio transformers. Our dual ration transformers (13kV/4kV primary), however, were greatly affected with respect to weight and size. The majority of cases where we need to replace a dual ratio transformer, require us to change the pole. The issue is compounded on “lot line” work where we cannot get a truck to the location. In these cases, men must manually pull the transformer up the pole to set it. This class of transformers is where we have started doing mo re refurbishment of used units to help resolve the replacement issues.

We are also concerned of the increase in wei ght with respect to our truck capacities. Our Digger/Derricks which are used primarily for pol e replacement but can also be used to lift a transformer are rated at 1,590 lbs. max. Our bucke t trucks, which we buy equipped with a jib for lifting equipment, are our primary truck used fo r lifting transformers. They are rated from 660 lbs to 2,000 lbs. max depending on how far the jib is extended. As transformers get heavier, the ability to use of a truck to set transformers is lost thus driving up transformer replacement costs to “lot line” type levels as di scussed in a previous email.

Finally, I would like to restate my concern with transformer size. When we talk size problems most people think of the vault and network type transformers. While these are a concern, my main concern is the size of pole type transforme rs. We in Baltimore (and I assume most large cities throughout the US) constantly battle to ma intain safety clearances from other utilities on our poles and also from public infringement on th e safety separations set by Code. In a congested city like Baltimore, even minimal changes in the size of a transfor mer can lead to major work to ensure the safety clearances ar e maintained. I know the goals ar e to improve air quality, but thecertain death from electrocution is an even more ominous affect that could result from the changes being proposed.

Hello Ken:

Thank you for developing this info... It looks like DOE wasn't too far off in assuming cost of $2000/per pole change out...The only other remaining question left that needs addressing is...

"When" does pole need to be changed? IE : What are "Engineering Rules/Limits" that result in pole change out...

Once we know that, we/DOE can estimate change-out frequency...

Thank you.

Best Regards,

Mahesh

Richard and Committee: Attached is a spreadsheet showing the cost to replace an existing pole in a three-phase distribution circuit with an ex isting single-phase dist ribution transformer mounted on it. This information was developed to estimate the cost to replace an existing pole with a new, higher strength pole required because of the increased we ight of the distribution transformer. This estimate represents the cost to do this for my Cooperative. Other Utilities will be furnishi ng this information for their systems. Kenneth A. Winder, PE
