April 20, 2011 – Powerline Problems

The last few days the turbine has been shutting down during times it should not.  I checked the diagnostic software that transmits info from the turbine itself.  The software reported that the grid voltage was not ok.  Line 1 voltage was at 133 and line 1 at 120 (the voltage should be close to the same on both lines). I called the power company, and within 30 minutes there was a truck here to look at the problem.  They thought it sounded like a neutral problem and it looked like the neutral wire connection near the transformed was bad, so they reconnected it and it was fine for a while.

The next day it was reporting the same problem and the lights in the house were slightly dimming and brightening.  I called again, and this time they found a problem on the pole in our yard.  One of the hot wires had lost its plastic coating and had evidently run against something it wasn’t supposed to touch and it looked like it had arced and melted about 1/3 to 1/4 of the metal strands that supplies power.

The red circle shows the replaced section of wire.  This tells me that the Skystream is a good forecaster of future household electrical problems and it does a good job of protecting itself  in the case of a problem with the quality of electricity coming to the house and turbine.  Kudos to Consumers Energy for promptly responding and fixing the problem!
