I am a hospital engineer in Australia. The generators we use take between 10 and 20 seconds to start for a black start (zero grid connection). 305kw turbo diesel Yanmar.
That's not bad at our local hospital here we have 4 caterpillar diesels 1500 KW each which the original contractor hired had them starting within around 12 to 18 seconds but the hospital complained it was too slow and had the generator company we deal with at the school district come in and make some changes and has them all starting and synchronized within eight seconds which is pretty impressive only three of the generators are needed to run the building so after a period of time the fourth will shut down
@@peterryan7340 not exactly sure how much they are running there but assume pretty much everything with that large of a emergency supply the UPS's I'm sure only do critical loads to cover the start up time but I would have to assume other loads are likely almost all on generator power I haven't had a detailed walk-through on their system though so I couldn't tell you exactly just from what I've seen and heard
@nics-systems-electric we load shed our chiller units, have 80kwh storage for UPS until generator supply initiates. The only AC we have during grid failure is Operating Theatres and Communications Rooms. Our total load is actually very low as energy efficiency is critical nowadays
@@peterryan7340 that's interesting I'm assuming we keep our HVAC system running as well as elevators which are another huge load and all lighting that leaves me wondering what actually isn't kept going not sure if the generators there are 1500 KW at 600 V or at 208 V but either way it's a large supply it is pretty impressive that they have them starting in around eight seconds now I'm not sure why the hospital complained that the 12 to 18 seconds before was too slow as the UPS's should be more than capable of covering that time other than you may lose your general lighting for a short period of time
wow...a 4 cyl perkins...made in the UK..funny to see it all the way over in canada esp mated to a generator head....over here they were a go-to for small minibuses and tractors
The place where I do facility maintenance at with 5 other engineers, we have 6 generators. The oldest one have is diesel the rest are natural gas and I asked when I first started is if there’s a disaster they’ll probably turn off the natural gas but on grounds we have a 200 gallon diesel tank to fill equipment wouldn’t it be better to run off diesel.
Nic, what model is that simplex panel in the backround. i heard it's trouble alarm go nuts during the transfer to emergency power. is it still being used or is it getting replaced with a new system sometime. just curious and greetings from Orlando, Florida.
@@nics-systems-electric Thanks nic, also about your generator situation at home. I also don't have natrual gas service where i live in Florida but i do have a whole house generator but mine runs on a big propane tank in the backyard. just a thought for you at home dude. Came in handy when Hurricane Ian and Nicole hit my area. Power went out and less then 2 minutes max i was back online. My whole house gen is a 20kw kohler. Runs everything including my well, pool pumps etc.
@@jcc3279 yes that is an option if you have propane however due to the cost and limitations on how it's allowed to be stored gasoline was my only option
@@nics-systems-electric oh i understand but you could have a tank put in depending on costs but i know about how it's stored etc. we had our tank put in when we bought this place. wasn't cheap but it was so worth it.
Why does that school have two Fire Alarm panels? I see a Simplex at the beginning of the video then when you turn the power off I can see the EST fireshield.
There's three panels in total the simplex 4100 Plus is the main panel and the EST fire shield is the theatre panel that opens the roof and there is another panel in the commercial kitchen for the suppression system
The ammeter on the transfer switch is definitely pooched, as it didn't even twitch when it transferred over. The one on the genset itself is also likely bad... I imagine the transformers alone account for 10 amps or so, so sitting at essentially zero is bollocks.
Yeah it was pretty fast if it wasn't below 60 it had barely just got there this one doesn't wait around to make sure things are stable it just throws load at it lol

they were common over here for tractors from the 50s to the 70s too

That generator will last for many more years, runs smoothly, could probably power a lot more of the building with it.
The way the generator came on, it sounded like a truck turning on. But nice video
you weren't sure about the year of that generator, it's right on the tag you were looking at @10:16 May 1996, is when it was built.
Yep I saw that afterwards
7:55 The generator has now entered its cool-down period
Loves the 60hz sound at the beginning by the way the video is school
That generator looks like it will need to be fueled soon that fuel gauge looked like it was at half or maybe a little over.
If the gauges is true I wasn't paying attention I didn't see one who knows if it's accurate
Love these videos
The power generator looks like hooting the car engine
Why is the generator so rusty

4100 plus. no replacement planned yet

I think the same engine is in narrow board here in the uk.

Yep it's definitely done
What does pooched mean?
@@GaryBeltz no good, dead, fucked, broken, done, defective etc.
Do the generators also get serviced?
Yes every year at the 2 hour load bank test
Is that the siplex high school?
Yes one of them
3:01 startup (sounds like a propane bus)
International icce
Looks like it transfered power before if even got up to operating speed(60hz) . Definitely weird 😆
Yeah it was pretty fast if it wasn't below 60 it had barely just got there this one doesn't wait around to make sure things are stable it just throws load at it lol
@@nics-systems-electric yeah. It just wants to comply with nfpa110 😂😂😂😂😂😂😂😂
@@thestihladdict1743 yeah which it doesn't even need to as it's a school lol
I need one of these
A ceiling light made by holophane 2 on and one off
I love you nic
7:46 it’s scare him little bit😅
Go back to 7:38 then wait
@@Mikey-x4l it's always a bit of a jump scare when you're sitting there for like two minutes waiting for it to go bang lol.
@@nics-systems-electric I had a hurricane and our power keep going on off on off
Huh Interesting stuff.
