Dear Electricians in training,
You have the unique pleasure of taking a "virtual field trip" to a water plant. In the video, an electrician from a water treatment plant will show you how electricity makes the plant run,which in turn supplies people with drinking water in their homes. You also need to watch the electric safety video (taken from Electricity and Magnetism, courtesy of United Streaming).
Your assignment is, first, to watch both videos, then use your questioning skills to ask the electrician about the plant or his job. He will answer you, so make sure they are good questions. :)
Have fun watching the videos, you will see many different concepts about electricity that we have learned already. The questions are due by THIS THURSDAY (December 18th). You will work with your partner and post your questions in the comment section. Make sure you leave your name in the comment section. Also, make sure you edit your questions or comments!

Dear Robert
I thought thoose two videos were cool,we have been doing alot of electricity in my class.
And my question is what is it like working on generators and motors? Do you ever get hurt,is it a dangerous job?
From Gianna and Zay
dear Robert,
We think your job is interesting also dangerous.
How tall are one of the generators?

Dear Robert,
I would like to see one of those big generators up close.
What is the most important thing to remember when working with electricity?
Abigail
Dear Robert,
I thought the video was interesting. How long does it take to clean the water when it leaves the lake? How many engineers work in the water treatment plant? Is your job dangerous?
Taylor
Dear Robert
that was awsome best thing ever!
how big is the genarator?how do you ever get hurt?
from:devonte and lane
cool nice viedo u rock
Dear Robert,
Those are the COOLEST videos that I have ever saw for electricity.
My question is.....
How can you tell the differance between a generator and a pump???
Karsie
Dear Robert,
I liked those two videos. They were awesome.
How tall are the generators????
From Adam and Stephen
Dear Robert,
How come it will burn you if you dont wear your suit and is your jub dangerous?
Thank You,
Andrew and Geoffrey
Dear Mr.Robert,
I thought the video was great about electricity. My favorite part was the generater. How tall can a generater get? My favorite part about the video was when you showed us on the board how the circuits flowed and how you showed us how the generater looked big and small. Don't you ever get hot in that vest? When ever you are working in your shop why do you like to help save the planet and make the world a better place? My brother keep putting stuff in the sockets and my mom went to the store and bought a cover for the all the sockets in the house. Mr. Robert the vidoes were great bye. From: Bryneka and Kayla
I would like to start with a question for you. I left out some very important information about a generator. It has to do with the speed the engine rotates. Can anyone tell me what unit of electricity gets affected if a 4 pole generator does not stay at 1800 RPM? (I will give you a hint. In Europe this always stays at 50??? And in the US, it is always 60???) Write your answer on the blog and don’t forget to leave your name!
a think it goes about 80 rpm.ANDREW SKINNER
Robert is the answer hurtz

For all who asked about how tall a the generator was:
That generator set is about 7 feet tall and a about 20 feet long including the diesel engine. THe engine is over 2000 horse power. The generator alone weights about 12,000 pounds. Each generator uses between 60 and 100 gallons of fuel each hour. We have 3 at the plant so that is between 180 and 300 gallons per hour. BUT WE MAKE A LOT OF POWER!! There are bigger generators out there. Mostly Power companies use the bigger ones but they don't get much bigger for privet industry.
For all who asked about the danger of the job:
Electricity is alway very dangerous and should always be respected and ONLY worked on by a trained professonal. According to online research, about 1000 people die each year from elecric shock. A lot of them are work related.
Please pay very close attention to all electical safety warnings they are there because someone found out the hard way what not to do. I am alway very careful and have learned to respect electricity.
As far as the suit we ware. Yes if uses for long it can get hot in them. They make them with cooling fans but the ones we use do not.
Karsie, great job! Hertz is the correct answer. Also known a frequency. When a four pole ac generator run at 1800 rotations per minute, the electrons change polarity from posite to negetive 60 times per second. I know it was a hard question but I could not talk about generators without you knowing that. It is important.
Abigail, always remember that electriciy is a luxury and leave the working on it to a trained professonal. Read and apply all safety labels and SAFETY SAFETY SAFETY!!!!!!!
and More SAFETY. Thanks for you question. Oh one more thing SAFETY
Electricity deservse respect.
Taylor that is a good question. It depends on how much water is being used by the users. I would say on avrage 3 to 4 days from the lake to the pipes leaving the plant. In the summer a lot more water is being uses for watering grass so it takes less time to go throught the plant. We call what you are asking about detention time. It means how long a substance (water in this case takes to go through an area. Thanks for the question.
Karsie, good question. The thing about you question is what is harder to tell the difference between is the motor and the generator. There are several different kinds of pumps and they look so different it would be hard to describe all of them. But what you saw on was the motor on top of the pump the pump was actually in the water below the motor about 30 feet down so I could not show it on the video. The give away between a motor and a generator is that the generator has to be driven by something like a engine where a motor alway is driving something like a pump or a fan. There are several things that are driven by an electric motor at your house. Can you name a few?
I will reply some more later. good night.
Dear Robert,
Did any body ever die?
if you don't wear the suit what will happen?
I think that working at a power plant is very cool because it's like your a person that helps the world. because you give every one clean water.
Amber Drake Casey!
Dear robert
Thank you for answering our questins. I think that was very nice of you to make that video for our class.
From Gianna and Zay and the rest of Mrs. Bonham's class
