Wind Generator Repair Work on the Rise


H&N Electric has worked long and hard (and waited patiently) for the opportunity to get into the wind turbine generator repair market. Out waiting warranty periods and the bureaucracy of the OEM's was worth the effort. H&N Motor Repair has been fortunate to have a number of wind turbine generator rewinds in our shop over the last number months. We have seven generators in the shop for major repairs and rewinds with more on the way.

The wind generators are notorious for having design problems from the OEM, and we have been hard at work to find solutions and upgrades that will greatly extend the service life of the equipment. For example, in the Weier generators the cause of failure has been coil-to-coil shorts due to the lack of coil-to-coil insulation from the OEM. Not only have we corrected this problem, but we have found many other ways to make our rewinds superior to the OEM. We have gone to great lengths in time, effort and expense to set ourselves apart from our competition by using superior rewind materials. This coupled with employing some of the best technicians in the country has set the stage to make us a leader in the wind turbine generator repair market.

Generator Enhancements:

  • Upgraded from three turns of 85, 1.12 mm standard magnet wire to quad-film magnet wire and are installing three turns of 51 number 15's giving the same circular mills per amp but a much more robust winding 
  • Upgraded to double slot liners and Nomex/Capton/Nomex coil separators
  • Added coil-to-coil insulation by glass wrapping each coil extension (the OEM has NO coil-to-coil insulation)
  • Duplicated the OEM's heavy tie cord
  • Double VPI using Elantas E-478LV Epoxy resin

The Season of Giving

The Wazee Electric office is collecting shoes for Soles4Souls, a global not-for-profit institution dedicated to fighting the devastating impact and perpetuation of poverty through the distribution of shoes and clothing. Soles4Souls collects gently worn shoes in the US, and then distributes those around the world to more than 127 countries including the US. All types of shoes are welcomed and appreciated, from tennis shoes to stilettos and hiking boots, and anything in between. Every kind of shoe can be of use to someone.

Gently worn shoes are distributed once they are received. Those that are more than gently worn are sent to countries where they are distributed for refurbishment, creating a micro-enterprise which people can earn income to support their families. Non-refurbishable shoes are recycled and made into other products as part of a Waste to Energy program. Nothing of use will be discarded. You can help add to this number by dropping off shoes in the bin outside of Karen's office.

Reduce the Risks with Personal Protective Equipment (PPE)

You've undoubtedly heard some horror stories about workers who were injured because they weren't wearing PPE that could have kept them safe. Year after year, work accident statistics show that an alarming number of injured workers were not wearing PPE that could have prevented or at least lessened the severity of their injuries. Think head to toe protection and be sure to consider all the hazards: falling objects, chemical exposures, flying objects, sharp objects, rolling or pinching objects, etc., as well as all the proper protection: hard hats, safety glasses and goggles, respirators, gloves, safety shoes, etc. The better you identify and understand the impact of specific hazards, the better able you will be to take the next step and select the most appropriate PPE.

Of course, engineering controls, work practices, and administrative controls are the preferred methods of reducing or eliminating hazards. Remember that PPE is a supplementary form of protection necessary where all hazards have not been controlled through other means. Although even when they have, PPE is still advisable in most cases as a backup. In our line of work however, PPE is required in our shops and on our job sites.
