    Calvin, with a little further attention to detail, the photo shows a downed low voltage power line in a residential/ commercial area. The main power line which is probably 69 kv is not that line. It is higher , and usually more remote from buildings. To lose 50 communities, for an extended period, suggest problems on the main lines. Perhaps you have knowledge of the details?

    Calvin, I admit I am not as "TOP" as I once was. And with only 3 or 4 engineers dealing with these problems, all were near the top. Salt contamination was an accepted serious problem, in so far that the Northern Pensinula was and is a secondary priority as compared to St John's. And there was no simple solution. I , and no other , was 'top' enough to find a solution to the salt spray problem. Sometimes engineers have to buckle to mother nature. I trust my memory is sufficient to recall that that area was very troublesome for salt spray problems.As they say , you attack the messanger, and ignore the message. When you factor out direct wind damage, salt spray was the most often cause of problems on the Northern Peninsula. Another article said 50 communities were without power? With these outages and recent ones,how many are salt related? I asked the question, has there been a solution for salt air flashovers? And how can it not be a contaminant, and a serious risk factor for Muskrat falls reliability?You know outages there get little attention in St Johns. If they affect St Johns it's a different story.

    Read the article Winston, a roof blew off of a structure and knocked down the lines, I imagine you were one of Hydro's top engineers with that kind of attention to detail.

    There have been repeated outages on the northern Peninsula this past few weeks due to "storms". This area is exposed to salt spray blown inland which causes flash overs and outages. It is likely the worst area in the province. As an engineer with Nfld Hydro in the 1970s I was familiar with this. This is now the route of the Muskrat Falls line. And their report said salt is not a contaminant!. I feel this is a seriious misrepresentation of the reliability of this transmission line. I have raised this issue a number of times, yet no media seeks a clarification from Nalcor. Have they solved the salt problem? These present outages suggests otherwise. Sure a storm caused it. But lots of storms don't result in outages. Were lines knocked down? was it lightning? Was it salty air on the insulators? St John's residents take heed, as this problem will be one for the capital when Muskrat is our source.
