Can wearing rubber slippers cause static reaction?

Topic: Reducing Static Electricity Shocks

Question

March 10, 2015

Can wearing rubber slippers cause static reaction?

Marion - Kenya

25821

Answer

When rubber slippers rub against the dry skin of the foot, it can create a slight amount of static electricity. Rubber slippers sliding on a floor probably would not create static electricity.

Insulation for ESP casings

Topic: Uses for Static Electricity

Question

February 21, 2015

Dear Sir;
I want to know if the thermal insulation of ESP casing mandatory.
Will ESP performance get affected for non insulation and how/ why?
Regards

Virendra - India

Answer

The insulation for electrostatics is not necessarily thermal insulation. Rather is is electrical insulation. That means it is made of nonconducting materials.

If items are not insulated, there is the possibility of electrical conduction, which you may not want.

Applications of thunder and lightning

Topic: Static Electricity and Lightning

Question

February 16, 2015

what are the applications of thunder power generation also about lightning

hima bindu - India

Answer

Thunder is simply the sound that is created from lightning. It has no real application.

Some have tried to harness the power from lightning. A major problem is that lightning strikes are not very predictable.

Has problem with cold weather hair

Topic: Flyaway Hair

Question

January 19, 2015

Dear friends, I live in a climate where the cold weather causes the static problem not only for myself but also for my two black cats with medium length hair. What would be a safe solution for "cold weather hair"? Any insights would be greatly appreciated.

Valeria - USA

Answer

In cold weather, the air can get very dry with low humidity. Not only does it cause flyaway hair and extra static electricity, but it can also make your skin dry.

It might be worth it to get an inexpensive humidifier to use in on cold, dry days. Even boiling water can put some humidity in your house.

Note that when the air in the house is very dry, you are more apt to catch colds and such.

Hopefully extra humidity in your house will help you and your cats.

Gets shocks from light switches in ocean front house

Topic: Reducing Static Electricity Shocks

Question

December 30, 2014

I live at the ocean front and often we get small shocks when turning on a light or power switch. Someone said it was static electricity shock from salt build up or humidity. What is it from and is there anything we can use or do to prevent it by cleaning the switches with something or some other way

John - Australia

25673

Answer

Typically, ocean front areas are more humid and not prone to static electric shocks. If the sparks only occur when turning on a light but don't happen elsewhere in the house, perhaps the problem is caused by some slight electrical short due to salt buildup in the circuitry. That may be a long-shot, but it is worth considering.

If the shocks occur elsewhere in the house--like when touching a door knob--that could be static buildup from your clothes.

You might check if any of your neighbors have had such a problem.

Best wishes in finding a solution.

Can copper get statically charged?

Topic: Static Electric Materials

Question

December 28, 2014

I am an amateur archeologist from India , I have heard that certain alloys of copper or just copper has the tendency of getting statically charged and can attract few grains of rice for a few inches and can retain this electric charge for a considerably long time .could you help me know how it is done?

Pradeep - India

25669

Answer

Newspaper companies sometime used copper brushes are to draw off static charges from moving rolls of newsprint. However, they don't really hold the charges.

There are devices called "rice pullers" made of a copper-iridium alloy. However, these are typically scams used in India to dupe unsuspecting people.

Since copper is a good conductor of electricity, it really can't hold static charges.

Preventing sparks in textile spinning industry

Topic: Static Electric Materials

Question

November 29, 2014

I would like to know how spark will occur when cotton and polypropylene both passes throu the GI metal round pipe by air suction around 1300 suction pascals?? Because we are recently facing frequent fire incident in our textile spinning industry. Especially at night time. Here climate was so chill with dry mist at very early mornings. Most of the incidents happen at night time and some case around morning 9 to 10 am... Please advice and help me to prevent from fire accident..

Satheesh - India

25602

Answer

The newspaper industry often use grounded copper brushes to draw off static charges on the moving paper sheets. Also, gasoline trucks ground their hoses when at filling stations.

You probably could use some sort of grounding scheme with your system.

See Controlling Static Electricity for more information.

Best wishes on solving the problem.

Chances of causing spark with brush

Topic: Static Electric Materials

Question

November 29, 2014

I would like to know if any chance of spark (Static Charge) while Polypropylene rub with nylon brush and fine steel wire combination?

satheesh - INDIA

25603

Answer

The steel wire would likely draw off the charges to lessen any chance of a static spark. You probably have nothing to worry about.

Demonstration with Van de Graaff generator

Topic: Generating Static Electricity

Question

November 19, 2014

my company wishes to use a vdg generator at a show booth. the concern is that it will damage electronic devices cell phone computers etc. is there a safe wattage for this thanks

robert - USA

25562

Answer

The article Van de Graaff Generator Safety recommends keeping electronic devices 20 feet away. However, they may be extra cautious in that number.

More importantly, they advise not connecting computers, etc. to the same circuit as the generator.

I hope that helps. Best wishes with your demonstration.
