Not only do we have the noise problem described earlier, but when the turbine is running slowly, it produces stray voltages at high frequencies. This is having bizarre effects on some electrical equipment in the farmhouse. Fluorescent light tubes buzz like mad, the hi fi buzzes, our super new electronic bread maker won’t work, strangely the interior light in one of the fridges won’t come on. Apparently it is to do with one of the inverters that convert the variable frequency AC voltage from the turbine to DC, and then back to AC again at 50 hz to match the mains. We are waiting for some filtration equipment to be fitted which should cure the problem.
