    They don't have enough money to pay me to do high voltage electrician/line mans work! Nothing but respect for anyone that's willing to put their lives on the line for all of us, especially the local utility workers out in thunderstorms trying to work on HV power lines in a storm! Thanks to all of you electricians. You keep our homes warm & lit & we appreciate it/you!

    FAQ for this video: *What are those suits they are wearing?* Those suits are AR (arc rated) material that would protect the workers from the highly destructive energy if a fault occurred while they were performing their switching. THESE SUITS ARE NOT FARADAY SUITS. *3000 KV? That's super high voltage!* This is not 3000 kV. This is a 3000 KVA (or 3 MVA) transformer. All transformers are rated in volt-amperes (VA!). VA is a capacity rating for a transformer, and could be compared to watts. That's the short explanation. Google true power vs. apparent power if you'd like to learn more about the difference between volt-amps and watts. *Why don't they close those switches remotely so they aren't in danger of being electrocuted or burned?* This could be an older facility, or the company just doesn't want to pay for automated equipment. That might sound crazy, comparing the value of someone's safety to the cost of remote operated actuators for disconnects, but it's the harsh reality. *What's that noise?* That noise is the transformer vibrating. Transformers rely on magnetic fields for their operation, and stray magnetic fields cause the transformer parts to hum in tune with the frequency of the electricity passing through the transformer.

We also repair and troubleshoot machinery, install new lines, program robotics, etc. The pay grade really depends on your skill/the danger level as the trades are more of a meritocracy. You're looking at $75k to $110k per year for a bigger company and about $50k to $80k for a smaller company. PS. I live in Canada so I'm only speaking from experience in Ontario.

    No, the "levers" each control a separate source to the transformer. Each switch has 3 blades, one for each phase and are all operated at once to turn on the medium voltage input to the transformer. This is why these switches are referred to as "gang-operated medium voltage load interrupter switches". I actually worked for Square D (the manufacturer of this gear) and started up hundreds of these types of installations.

They are to protect you from the fire until rescue teams can help you.

    There is indeed an expression for the reason of that "hum" coming off from transformers under load : "magnetostriction". And often, this gets louder if a transformer is on its "operating temperature" (or gets overheated in an unexpected situation of overload) when the lamination gets a bit more "loose" as the winding bodies expand in some way.

Did a project the other day where the incident energy was above 100 cal / cm^2 at 208V. The transformer secondaries are the worse coming off of utilities. It all depends on the clearing time of the upstream protection and the cleared fault threshold.

    kVA's are not volts, they are the product of kilovolts x amperes x power factor. 3000kVA at unity (=1) power factor = 3000kW or 3mW. This is still a huge amount of energy to be around if things go wrong. To put things in perspective, 3mW equates to approximately 4,020hp. It's possible to have high kVA circuit ratings at relatively low voltages, there just needs to be lots of amps.

My Dad worked for the local electric company, so the meter readers and linemen were my childhood companions. My favorite video of yours is the one of switching on two transformers at a substation. T2 really growls with the inrush current!! Music to my ears with that 50Hz roar. I know you are from New Zealand from your videos and I have several friends there. One on the South island and one of the North island. To have a response from you is a real honor! I love your videos that range from educational to destructive testing. I have been in electronics for 30 years and love seeing things from another country. Oh, the reason transformers hum is because the laminated covering of the windings. They allow for the vibration. =) You are awesome sir and keep putting out the videos!!

    Back when I was a teenager, I remember adding a circuit to this old zinsco panel in the basement to run my computers. There was no main breaker, and didn't want to piss off the power company by removing the meter seal, so I worked on it live. Makes my spine tingle now I see you have to wear a damn space suit just to turn it on with the covers closed.

    Yes, while I don't know about this installation, it is generally around 1-5kV. The "explosion" is called arc flash. When the switches are opened, an arc can jump the gap between the contacts; when this happens, the arc heats to around 30,000 to 40,000 degrees F, and due to thermal expansion of the plasma of the arc, and the air around it, a pressure wave is formed (the blast). The protective suits help absorb & reflect the heat and intense infrared from the arc.

    The first time you close up any high energy switch the adrenalin is pumping, doesn't matter how many checks how many tests, there's always the what if's. That's also the reason for the flash suits, to try and stop some of the molten copper and the Ultra Violet flash if something does go wrong, that's also a good reason for the video recording. So the next guys don't make the same mistake.

    They are called arc-flash suits and are used for thermal protection from burns in case of an arc-flash failure. It is a safety precaution. The suit rating is based in cal/cm2 and it determined by doing the arc-flash study. All of this is spelled out in the NFPA 70E. BTW, they are not the same faraday cage suits that are used on HV lines.

I was tasked to slide into the buss lockers with a plastic can of distilled water. To top off the emergency batteries for the load switches. Nothing like sliding past hissing bare busses and your skin getting pimples. As the senior guy says, "Watch out for that one, that's 300k." Just stick to the opposite wall and you'll be OK. Note: Those lockers were not wide enough to walk into straight anyway. (if you dared.)

It housed the building disconnect and a pair of 5KV/440V transformers. Over the years the hum from those transformers just gets louder and louder.

    Retired from a large hospital/research centers that had 17 13,200 volt switchgear & transformers. Larger research building required 50 CAL suites and everywhere else required 40 CAL suites for racking in 13,200 volt gear. Had a remote site that had garbage POS GE 13,200 volt dual service outdoor equipment. Genius GE engineers out did themselves on this . Not only had a CAL rating of 124 but they installed vents at eye level where you had to perform the switching. So in the event of an arc flash they would provide free instant cremation. Showed my inspector a picture of the 124 CAL Arch fault label. He told me he never saw such a high rating. Was told at continuing education classes that 60 CAL is the highest # suite they make. Told us even if you had a 60 CAL suite on the arch blast would blow you 20 feet across the room and blast will kill you. Of course this being GE Junk and I had trouble with every GE 13.2 KV switchgear that I had to switch or rack in. This particular garbage GE like other outdoor units that I switched had problems with humidity within 6 months of start up where they had to install heaters inside of gear to keep moisture level down.

    No its so if the contactors arc over and they are enveloped in a ball of plasma they aren't burned to death.

    No, its to protect themselves from arc flash. Plasma gas that will readily burn you to a crisp. Those are basically fire suits like race car drivers wear.

    No, usually there's no such mechanism. During the switching operation the contacts will produce an arc. That's why all switches have arc quenching medium or mechanisms, no matter which voltage. (LV features installations to cool down the arc, MV works in vacuum with field-controlled chambers, and HV works with directed flow of SF6 or air, depending on the type of switchgear)

    @evhgl87 when you put the contact with slow motion force on the lever, you have a slow action with your hand but in the internal of the switch, there is a contact on a spring loaded toggle who make the contact very very fast. It what make the sound your heard "clac".
