RAIN
One odd non-barking dog ... normally when we get rain after a period of dry dusty weather, lots of power transformers pop. Water + dust = arcing path between terminals. This rain comes after TWO MONTHS of EXTREME DUST and GREASY WOODSMOKE. It's been raining for two hours now, and no popped xfmrs yet. Maybe yesterday's wind cleaned the xfmrs.
Later: Spoke too soon. Or non-barked too soon. After another hour of rain, there are about 7 popped xfmrs and pole fires. Nothing abnormal after all. Oddly, these pops caused a LOT more actual outages in Spokane than yesterday's wind.
Seems like a solution should be available. Mounting the xfmr upside down, with terminals on bottom, would solve rain, dust and squirrels all at once. Indent the bottom so rain and dust can't flow there under any circumstances.
