Power Hungry


Friday Evening, November 30th 2012

This is a test of the emergency broadcast system…except that it’s not a test!

We are in the middle of a complete power failure, neighborhood wide. Sometime back, I bought a UPS, and hooked the cable modem and router into it. It’s rated to run a full computer system…including the monitor…for 10-15 minutes. Since I’m using the laptop, and the UPS is only running the modem and router, it should be good for at least an hour.

We’ll see!

Or hopefully, not. Having the power off is annoying, if for no other reason than the heater doesn’t work. I recently tested the generator, and it’s working fine, if it comes to that.

Maybe I should fire it up. That will pretty much guarantee that the power will come back up as soon as I get it running…

 
Saturday Morning, December 1st 2012

The saga continues…we’re still getting power burps this morning, which is more than a little weird. It’s not snowing; it’s barely drizzling. It’s windy, but it’s been far windier than this with no problems. Similarly for the rain. But, this is the worst stream of power failures since 2005, which was the catalyst for me buying my generator.

One thing for sure…I am sick and goddam tired or resetting clocks! The major outage yesterday evening was over two hours, but there have been numerous burps of minutes or seconds since, one just about 20 minutes ago. And, tonight is supposed to be The Big One of this sequence of three storms, so there may well be power issues tonight.

In a way, this has been a great test opportunity. I’ve done a lot of general preparation for power outages (a good thing), but I hadn’t run a full-up test of the system since doing so (a bad thing). Since the weather conditions weren’t those that I would expect to cause a power failure, I didn’t do any special preparations, or get the various pieces “staged”. That made it a true surprise, a “cold” test. So, I’ll describe what’s happened so far, which may be useful or informative to some of you, and describe some of my next steps.

For background, when the lights go out up here it gets dark. Not the wimpy dim-light condition that city-dwellers refer to as dark, but seriously dark. On a moonless night with the power off, you literally can’t see your hand in front of your face.

One consequence of this is that I keep a flashlight next to my recliner, which I use daily. So the flashlight is not an item stuck in the back of a drawer somewhere, that you can’t find when you need it, and that won’t work if you can find it. The flashlight always works, and it did last night.

I was watching the tube when darkness fell, and just sat for a few minutes, thinking it was a momentary burp. When it became clear that it was more than a burp, I fired up my computer, both to test my BCP process for communication, and for something useful to do. The process worked perfectly. As I mentioned, I have the cable modem and the wireless router hooked into the UPS. I cleared my email buffer, and then thought about what to do next.

There are a couple of non-technical background issues going on at this point in the evening. I’ve been sick all week to a greater or lesser extent, and last night was unusually bad. Also, my dog Xena was totally freaked by the power being out. I’m not sure why. I wasn’t the least bit concerned myself, so she wasn’t picking anything up from me. However, it turns out that a bunch of alarms go off in the neighborhood when the power dies. In any case, she wanted to be outside. The entire rest of the evening, she was freaked, not responding to her name…not even eating a snack I gave her. A couple of hours later when I went to bed, she got up next to me, and she was still shivering with fear. She’s better this morning, but she still wants out immediately whenever the power burps. She’s outside now. I was more worried about her than I was about the power.

I tested the generator recently (less than a month ago), so I knew it would work, but I didn’t know how much fuel it had in it, and I didn’t know if I could get to the gas cans with the garage door closed (With a mid-size SUV, four large motorcycles, and a bunch of crap in a small 2 car garage, it’s a pretty tight fit). Or how much gas, if any, was in the cans.

I decided that my first move would be to hook the inverter up to the car (in the garage) which would give me 300 watts. That may not sound like much (because it’s not), but having a single 100-watt bulb lit is remarkably better than sitting in the dark. I had to dig through the mountain of crap in the back of the car to find the inverter, but after that, hooking it up and getting some light in the house was easy.

The location of the light wasn’t ideal, however. The family room is my waking “hub” in the house, but it’s far from the garage. I have plenty of extension cords…but most of them are in a cabinet in the garage…which you can’t open with the car parked in it…and you can’t conveniently open the garage door without power. You can do it manually, but the process of disconnecting it, lifting it, and reconnecting it is such a cosmic pain in the ass that I would only do it in an emergency, which this clearly wasn’t. Finally, between extension cords and power strips, I was able to cobble together a cable long enough to bring the inverter power from the garage, to the light next to my chair in the family room.

The Bridge was no longer in darkness!

I don’t know how long a fully charged car battery will power a 100-watt light bulb through an inverter. Doing that calculation is on my action item list. But I now know for certain that running it for two hours has no discernible impact on the ability to start the car.

Feeling really crummy, I seriously considered just going to bed, but I decided to see the test through to completion as long as the power was out. My design configuration for an extended outage (which still hasn’t been tested) is to have the generator on the back deck just off the family room, run the power cord inside through a cracked window or door, and then power up…at least, whatever stuff I have enough power for with a 2000 watt generator, which probably puts out only about 1600-1700 watts at this altitude. You remember the scene from Apollo 13, where they had to come up with a power-up sequence for the CM that wouldn’t overload the system? I need to do that test. I know the generator will run the furnace, the refrigerator, or the microwave, but not two of them at the same time, never mind anything else. I may do that test in real time this evening by necessity, or earlier if I feel better later today.

So I took a small lamp out into the garage (the inverter has two 110 outlets), and determined not only that I could get to the two gas cans easily, but that one of them had gas…enough to top off the generator which, if I remember correctly, is good for 4-6 hours of operation. Checking out that endurance, and refilling both of those gas cans, is on the action list.

Just as I finished filling up the generator, the power came back on. I immediately opened up the garage door, fired up the car, and positioned it outside in such a way that I could run the power cord from it to the inverter with the garage door closed. That way, I could run the car at idle, and get continuous power to the inverter (running the car inside the attached garage would obviously be a bad idea). I set the cord in the appropriate position, and closed the garage door. So, if nothing else, I’d have at least 300 watts essentially indefinitely, if the power crapped out again.

The power burped a few times, but then stayed on, and I went to bed. I had to get up every hour or so to let Xena out or let her back in, so I ended up getting at best a few fitful hours of sleep in my recliner. I had a lot of things I wanted to get done today, but nothing that can’t wait, so it will. Hopefully the power will stay on through the Big One tonight. If not, I’ve got everything staged far, far better than I did yesterday.

Any of you have a recommendation for a UPS that can deliver 1600 watts for 5-10 minutes? That would be more than enough time for me to get the generator powered up, and once I get the “Apollo 13” configuration for my home “Bridge” figured out and set up, I’ll become reasonably indifferent to power failures, cycling the furnace and refrigerator on occasionally, as needed for climate and storage control.

A pain in the ass, to be sure, but also an adventure!
