Do you get frequent power outages? And when do you got it most frequently?

I don’t get nearly as many as I used to. They used to happen almost every night during summer afternoon thunderstorms, years ago.

I’ve lateley been getting some in the morning.

Had one about a month ago, it was a very chilly morning and it went off around 4:30 AM. It got quite cold in the house too. It came back around 6AM.

This morning I had power go off just before the 7AM. I was in the bathroom getting ready for work, and heard it flash 3 times and stay off, and I heard my neighbors automatic generator turn on. Fortunately I had my phone with me for flashlight.

I left for work just after, and I already saw bucket truck with searchlights scouring the power poles down street. It was a localized outage as I saw yard lights and porch lights on surrounding street were on.

It was still dark out and oddly foggy, and strangely no cars were around other than bucket truck.

Seems the power goes out for more than five minutes at least once a year in my area. More than the past recently. The power almost never went out back then.

For me, power outages happen during rainy season. The transformer down the lane can't handle water, and every year issues occur. These outages have killed several computers, and even all of my photos stored on it. Now, almost all appliances are on stabilisers and battery backups. As I'm typing this on my phone, a 30min long outage just occurred.

I remember there was a bad hail storm a few years back here in Canberra, the power went out for a while after some trees fell on the 240v lines. The blocks in my area are set up with one house opposite another, all the way down the street. There are power lines that supply the houses in peoples backyards, where there are also trees... Access for the local power company is annoying and replacements of the 50+ year old timber poles which are crumbling involves a large Mobil crane. The new poles are fibreglass though, so they're significantly lighter than their timber counterparts. Most of our transformers are pad mounted.

@rjluna2 Yes I have added a new ups. My old ups batteries decided to inflate, so while servicing I had to remove the ups. That was also the time power outages became common.

That’s one of the things that has helped here, as the last few years they have replaced all of the poles and equipment in my neighborhood area. So the poles snap much less frequently, even in hurricanes we get much less downed power lines, which means power stays on longer and gets restored sooner.  ;)

That's why I replaced these batteries every 3 years.

Here in my location power outages are extremely rare, also in strong stroms since power company buried underground medium voltage distribution line, which passed by forest terrain + they connected much residential areas medium voltage system in "ring" with automatic cut offs which disconnecting failed section from working one.

 I used to get atleast 2 of the quick 2-3 second power failures every week until I raised   >:D HELL  >:D with the utility company until they sent a supervisor out to look at everything . He found so many problems with the overhead wiring in my area that he filed an emergency repair order to get it fixed immediately ! He was astounded that the system was in such a bad state . I haven't really had a issues since...

We had a scheduled power outage that began at 9:10 and ended at 15:58. I think the IEC did upgrades in the substation at the beginning of Zevulun road, which located at the entrance of Kiryat Ata.

We almost never have power outages here, but last winter there was a lot of wind. Many trees fell and hit power lines. Most of Portland was without power for a few days.

Unplanned outages are very rare here. Maybe every 2 or 3 years for 2 hours or so. Underground infrastructure so there never is any relation between weather/thunderstorms and outages.

If things do go out, it's usually  because some underground splice made half a century or longer ago went bad.

2 years ago, however, there was an extremely severe failure on the 380kV national grid. A new substation was under construction, the line was grounded. Protection systems were not setup yet in at the substation in question, while the remote shutoff for the feeding station was not enabled yet because the new substation wasn't finished. People had to physically go to the feeding station to turn off power to the line Because of that, the overload on the 380kV lines was so big and long of duration they started SAGGING AND SMOKING over a distance of more than 10km, as can be seen in the video: https://www.youtube.com/watch?v=nyjCrP38ICc

Mind you, this is part of the national distribution grid, not a high voltage line in the street. The power levels are insane.

Absolutely spectacular and horrifying. Imagine being the farmer on that plot of land, out of view of the actual fault, and suddenly you see the 380.000v lines slowly start to get lower and lower and start to smoke... I'd run like hell.

At a certain point the 380kV lines intersected a railway line with 1,5kV overhead power, and it sagged enough from thermal expansion that it actually contacted the railway line. This in turn blew up the entire signaling system over more than 10km of distance.
It is the biggest electrical failure my country's ever seen. The people living around the fault area got their power back the same day from a different feeder, but it took many months for the damage to be fully repaired.

I live about 45km from it as the crow flies, and i noticed the faint light flickers from the fault pulling down distribution grid voltage.
