coming from a guy whos father is a electrician, you looking away from the breaker when you turn it on or off is fricken awesome

my neighborhood has like 135 of these things inside the leasing office to prevent concerns of houses going on power outages when theyres a power outage or a storm.

Nice video Nic, 😊 Nicely explained 😁 Good to see the generator and the system running and working as it should 🤩😉

I love your videos of the high school. Great as always! Dont stop posting!

We have an old Kohlar 39Kw LPG generator in our radio comms towers equipment shelter which we acquired from AT&T some years back, It's automatic transfer and powers the entire comms site plus it has a solar maintained battery bank and UPS that keeps the site equipment online including the tower lights during the time between power loss and generator transfer. She may be old but she has never failed us.

i love your videos on how fire alarm systems generator systems work and all the replacement on all the schools im really learning more about this stuff and things like that you have a good summer to come and thanks

Great vid as always! Keep it up nic!

Really cool video, I love seeing this stuff! Also awesome hearing the generator roar to life at 9:16

I’d like to see the light go out and come back on in the hallway as well. Every other light is powered by generator, so I’d kinda like to see that in action.

I have come across "Sender unit". It is the unit which measures the fuel in the tank. It is more specifically called a Fuel Gauge Sender Unit. Fuel Leak / Sender failure might indicate that the fuel pressure does not come up and that there is either a leaking hose or the fuel level is not true and does not trigger Low Fuel Level Sender failure might indicate that the resistance of the sender is not plausible SC/OC.

Amazing video! I love the thumbnail too

Explained good as always

We have the same type of thing at our datacenter, only it's a tad bit bigger at 500kva. Our two UPS's are 284kw and 140kw.

At 9:39 Fredonia Orange Bowl Concession Stand Light And Field Light And Scoreboard Turn On When Fredonia Orange Bowl Generator Start

Keep making great videos mate ❤

My school had quality asbestos and if you were in the PC room, the rule was to never turn on more than 10 PC's otherwise the surge protector for the PC room next door would switch off.

“Sender failure” possibly refers to sensors. I’ve heard engine oil pressure sensors referred to as oil pressure senders, I’m guessing it’s checking for resistance and/or voltage to be within a certain range to verify operation

The fuel sender is the mechanical float that measures the tank level. So that light comes on if it detects a sudden drop in the fuel level meaning ether the tank is leaking or the fuel gauge has failed.

They tested the generator at my work yesterday before it opened (it’s a department store at mall here in Florida). I was wondering if you can think of any reason why the lights went off three times instead of just twice when the loads switched as shown here?

I like when that generator started up. How often do you have to test it?

Hello I love fire alarm systems thats the reason why I love your channel I wish I could get a fire alarm system in my own home or something but I cant but I might in the future we just have to wait and see but I'm going to ask promotion to see if I can set of the fire alarm at my school for a good video but if there say yes I think it should be after school time or there might want a fire drill so there might let me do it and record it for content.

In my last comment on your channel I talked about mixed signals and you use that word alot. So I did some research on what it means.

There is not a CO detector. diesels produce much less carbon monoxide than gas engines so I guess it's not as much of a concern especially since it's exhausted outside and there is constant air movement in the room when it's running

Do you ever alternately turn off one ATS at a time to verify that particular ATS can start the gen? I know in a true power outage it may not matter, but at least in the US when it comes to hospitals you have to verify each ATS can start the gen. Which used to be rotated each test and I have seen 15 or more ATSs in some hospitals. But that way, if that one circuit trips for whatever reason the ATS is confirmed it can start the gen. But not sure how strict regs are for schools there. It's a school, not a hospital.

@nics-systems-electric

2 ай бұрын

It's not something you have to do. the generator just has to be started monthly you can just hit the run button to satisfy that requirement. I think I have started it from the standby transfer switch before just by doing a test with load from the actual transfer switch not switching the breaker off. Definitely not a bad idea to test all transfer switches.

Why do you turn off 2 subpanels instead of the main breaker for these tests.

@nics-systems-electric

There's multiple reasons. we don't want to shut down the entire building for no reason. You also don't want to be operating a large breaker under high load as it can fail. When you do a full building shut down you wouldn't be just opening the main breaker you would be turning off every smaller one first anyway.

Solar has its place but emergency power is not it. Not only the batteries that would be required would be extremely large and expensive that whole system would need to be CSA/ULC listed for life safety emergency use. we have schools with solar but not with batteries that would be just too big for a school. The solar system shuts down during a power outage and only the generator produces power at those schools anyways.

0:07 “60 kay double you” why don’t you refer to it as it’s real name? Respect derived SI units. I don’t even think it’s going to be kW. It would be KvA?

@nics-systems-electric

2 ай бұрын

It's not "Kay double you" It's actually 60kw which is a measurement of power. kW is a common abbreviation for thousand watt. and is not the same as kVA. Generators are usually rated in kW however often both are specified on the nameplate as with this one. 60 kW or 75 kVA. Hope that helps.

@inothome

2 ай бұрын

kVA vs kW... VA is Volts times Amps and with DC gives you the Wattage, k for kilo, M for mega etc.... When it comes to AC since the current and voltage will not be in phase (except a purely resitive load) a simple VA calculation will not give you your actual power output. You have to account for the power factor, which is the ratio of VA vs real power expressed as power factor. As a general rule of thumb they use a 0.8 power factor to derive the kW rating from the kVA rating. But in real world conditions the power factor will change based on the types of loads. Purely resistive loads are a PF of 1, a crappy motor may be as low as 0.5 unloaded. So transformers and generators are based off the VA they can produce not the actual Wattage, since the power factor is unknown. And yes, your toy 5,000W gen at home is rated by Watts for simplicity, but real generators are rated in kVA or MVA. As far as nitpicking kW vs kilo-Watt.... that's just being a pain in the ass for no reason. Anyone in the industry calls it kW, MW etc.... By the way, Watt is the SI unit for power. So kW is correct in SI nomenclature too. And for someone telling someone to respect SI units, kvA is wrong. kVA is correct. V and A are capitalized as they are respective SI units. The k is just the sign for thousand and is lower case.
