Your last generator Maintenance Run

[grsthegreat]

Ya, i have several backup ups, and there the only reason i am woken up during late night power outages. I tried, but have not found a way to prevent the beep. I can only silence them after they go off.

Though I own more than one tractor, I'd never have a pto unit simply because if we had a power failure, my wife would never be able to hook up the generator to the tractor in the first place.

Well engineered, installed, and maintained auto-gen..... huge peace of mind, and convenience.

In a past work-life (making better money), I could have caught a few deals on a PTO gen, but as I was on the road intensely for most of a month at a time Spring and Fall, would not have stuck my better-half with a PTO hookup either.... If I'd stayed on that work trajectory, would have a Generac Auto or equiv, in place here now.

With a tractor to spare, and someone to hook it up..... PTO is a good solution though, Watts/$.

Not only that, but at least below a few MHz, it will hurt the entire time it's doing it.

Might not stop your heart, but as you know, RF burns are no joke either .

I can relate to all the noise comments, we used to have a John Deere 70 (2 cylinder, Johnny popper) connected to a 15kw pto generator. Closest neighbor complained about the noise of the engine running and they lived a half mile away.
Sure loved the sound of the pop,pop,pop though. Brings back good memories!

The Sound of Electrons, Being Made !

Given a choice (extended outage), quiet is appreciated, but even a loud gen will get some love, if it is the only game around.....

Music to some, irritation to others...... I think it was a video of someone driving Twin Stick (an old Cummins anyway...) that I sent to a buddy out West a few years back..... really sweet sounding diesel - he said he wanted to put it on-loop, as a great way to Get To Sleep !

mind you, im a generator tech. i hate hearing about a quiet generator during an outage. cause thats usually a generator thats not working

Yep. I have stories!

And those guys working on big TWT amplifiers have both the high power RF and high-voltage supplies and exploding water jackets, all in one chassis. One guy I knew ended up getting himself across a 40 kV supply, when he was startled by a water-cooled load exploded in the test bay next to the bay in which he was working. I think he actually wet himself... in any case, he went home for the rest of the day.

Another customer was killed by RF burns, down in the VHF bands, when someone powered up our system while he was out on the test range. It cooked his liver, and damaged several other organs, he died a few days later.

Not many good ways to go..... that ^, must have been agonizing. Too bad, no Range-Officer/Lockout Procedure was in-play.

A few hams hang-out on TBN.... but a PSA for everyone else..... way below the power-levels WD is talking about, RF can injure. Eyes, being one of the most susceptible, even @ low-power levels....

Enjoy RF, but play safe....

Funny enough, testicles seem to be the most susceptible. More on that later, running out the door, now!

TBN - we keep more than just your generators running well !

I guess I had forgotten to come back to this, until 3930dave reminded me.

A female coworker at a prior job (Lucent/Agere) started noticing maybe 25-30 years ago, that all the male RF engineers only had daughters. The numbers were admittedly noticeable, like damn near 100% daughters, for the guys who did a lot of lab work. So, she started tracking it, and tracked it for several (5-10 years?), and over and over again... daughters coming from the guys doing a lot of lab work. These folks would have been doing mostly long-haul optical transmitter work, fiberoptic network backbone equipment, very broadband and relatively low power. Think roughly 100 MHz to 40 GHz, but only 0.1 to 5 watts.

Then I transitioned into high power amplifier work, and was working on systems up to tens of kilowatts, also broadband, audio band up thru 18 GHz. I began noticing at this new company, most of the engineers and tech's had only daughters.

We know RF energy causes heating in the most dense organ tissue, which is going to be your testicles and your liver, unfortunately two organs I hope to continue exercising beyond all others. It seems this energy exposure, whether through heating or some other mechanism, but be making the boy swimmers come out substantially more lazy than the girl swimmers.

Who thought that generators and swimmers would end up in the same thread!

 

[Robin Veerman]

Well it is a discussion on maintenance…..

Sorry. I found it interesting, but maybe too much thread drift.

No harm.... call it Equipment Maintenance.....

Not data I track closely.... but seem to recall at different times hearing about high proportions of female births, with endocrine disruptors being cited. Correlation/Causation..... can be challenging to sort-out.....

I play RF as a hobby.... not big on End Dis's though......

[bdhsfz6]

I think it was the discussion of governors that did it

 

[3930dave]

We're all about Mech Engineering here !!!!!

That's like the term it will get cold enough to freeze your
balls off. That came from the old sailing man of war ships
that had canon and the racks for the canon balls were made
of brass and when it got very cold the canon balls would fall
of the rack hense the term "freeze your balls off"

IIRC, those brass-plates were a "monkey".... so we got, Freeze the Balls off a Brass Monkey....

That is an awesome story! And I was so hoping it was true!

I did some digging on this, since it's exactly the kind of weird factoid I love, and unfortunately it appears this etymology is misappropriated:

It is often stated that the phrase originated from the use of a brass tray, called a "monkey", to hold cannonballs on warships in the 16th to 18th centuries. Supposedly, in very cold temperatures the "monkey" would contract, causing the balls to fall off.[15] However, nearly all historians and etymologists consider this story to be a myth. This story has been discredited by the U.S. Department of the Navy,[16] etymologist Michael Quinion, and the Oxford English Dictionary (OED).[17]

I thought it was interesting and humorous!

So more slight thread drift must be in order.

I worked for a company for several years that did nuclear research and made some reactor products that were consumables. But had long lasting effects to personnel exposed to the products in production. We had some similiar results in the reproductive area that you discussed previously. Except the swimmers in this case were sterile. So no boys or girls from this workgroup.
The product was radioactive and used in the generation of electricity.
