I Have to Feed Single Phase 100 KW Street Light Load by Using 3 Phase Genset.?

The first answer is correct. I just want to add the following to clear all confusions : 3 ph load = sum of all 1ph load in 3 phases = R-ph load Y-ph load B-ph load Since you have 1ph 100kW load and you want to connect the load from a 3ph genset, the capacity of the genset shall be minimum 100kW. Now considering an overall power factor of the lighting load to be 0.8 the rating of the genset shall be 100kW/0.8 = 125kVA. Hope this will clarify all your doubts.

1. A 6 foot man walks at 8 ft per second toward a street light that is 20 ft abovethe ground (cont.)?

Lets calculate the the length of the shadow when he is 15 ft from the light. First draw a diagram to make it easy to visualize. You get a trapezoid lying on it's side. Extend it into a triangle. Fill in the values on the diagram. 20 ft for light, 6 ft for man, 15 ft for distance, s for the remaining length of the base of the triangle. This remaining length is the length of the shadow. Now we have a large triangle 20 feet high, with a base 15 feet plus s feet. And a small triangle 6 feet high with a base of s feet. They are proportionally the same, so let's set up a ratio. Set up a ratio. 6/s = 20/(15 s). Solve for s, you will find s = 6.42. The base of the large triangle = 15 6.42, or 21.42. Shadow length = 6.42. Now move 8 feet toward light. Now repeat the above process at 7 feet from the light, using the same method. The shadow length now = 3 ft. Subtract the two shadow lengths, 6.42 ft - 3 ft = 3.42 feet. This is the rate of change per second of the shadow when the man is walking toward the light at 8 ft per second.

2. How to sell street light?

Not on a motorcycle forum

3. A street light is at the top of a 16 ft tall pole. A woman 6 ft tall walks away from the pole with a speed of?

who cares, her shadow is not doing anything wrong

4. What do you think about art?

To me, art is something amazing, and something we see everyday. Art is the people around us, and the buildings we see. Every car, tree, and street light, to me, is a form of art. Music is an art, as is drawing, painting, sculpting, cooking, dancing, writing, and all of that stuff. The talent, technique, quality, and originality of a piece of art is how you price it. There are some paintings that I could see going for millions, and others I wonder why anyone would buy it. Everyone has a different perspective on art and what they consider to be true art. I am a practicing artist, and I enjoy all types of art. There is not much more I can say beyond that.

5. Why does a Na street light give off a different color light than a Ne light?

Very simply yes. The light emitted is unique for each substance (magnesium for example gives off a bright blue light, sodium famously is yellow).

6. Street light intersections; on top of each light has the senors that tells it to turn green?

Your right there are sensors on top of the lights to change the light for emergency vechiles, as they approach the the light they can control the intersection. There are sensors under the pavement in some intersections that change the light when a car is stopped at a red light. It is a kinda a weight sensor.

7. How do i get a Street Light installed at my home?

either put one on your property (if you own your home), or simply carry one of those small LED flashlights that are available these days, they easily fit in a pocket or purse. I doubt your town will install one for you, that would be very expensive.

8. When you were a kid did you often break the street light rule?

I was never out of my moms sight untill I was like 13

Let's Talk About the Application of Thermal Conductive Silica Gel in LED Lighting Industry
Thermal conductive silica gel sheet is a widely used thermal conductive interface material. It is in the form of sheet, high pressure shrinkage, high reliability, high temperature resistance, excellent thermal conductivity and insulation, with viscosity on the surface, simple and convenient construction. It can be die-cut and punched according to the size and shape of heating devices.Heat conductive silica gel sheet is a kind of heat conductive medium material made by calendering with silica gel as the base material and adding various auxiliary materials such as metal oxides. It is usually called heat conductive gasket, heat conductive silica gel gasket, heat conductive silicon film, soft heat conductive gasket, heat conductive silica gel pad, etc. it is specially produced for the design scheme of using the gap to transfer heat and can fill the gap, It not only completes the heat transfer between the heating part and the heat dissipation part, but also plays the roles of insulation, shock absorption and sealing. It can meet the design requirements of miniaturization and ultra-thin equipment. It is a good heat conduction filling material with manufacturability and usability, and has a wide range of thickness and Application.Led thermal conductive silicon film is mainly used between aluminum substrate and heat sink, between aluminum substrate and shell, etc. Today, we mainly introduce the successful application of thermal conductive silica gel sheet in LED industry: there are many kinds of LED lamps. For indoor LED lamps, thermal conductive silica gel sheet with relatively low thermal conductivity is generally used, which can reduce the cost of the product and meet the needs of the product itself. For some outdoor high-power LED lamps, such as street lamps, the power is much higher than other indoor lamps, In order to better heat dissipation of lamps and improve the service life of lamps, thermal conductive silica gel sheets with relatively high thermal conductivity are generally used.The inherent viscosity of the heat-conducting silica gel sheet facilitates the construction. If the customer needs the heat-conducting silica gel sheet to have strong viscosity to replace the screw fixation, he can also choose to give one-sided or double-sided adhesive backing to the heat-conducting silica gel sheet. If the heat-conducting silica gel sheet needs to lock the screw, please remember to choose the heat-conducting silica gel sheet containing glass fiber cloth, which has the properties of anti puncture and anti tear. In short, the heat conductive silica gel sheet can be customized according to customer requirements to meet customer needs. It can be die-cut and punched according to the size and shape of heating devices.
