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.

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

Overall design of grid connected photovoltaic power generation system
The grid connected photovoltaic power generation system converts the DC output by the solar cell array into AC with the same amplitude, frequency and phase as the grid voltage, and realizes the connection with the grid to transmit electric energy to the grid. Battery pack can improve the reliability of system power supply. Photovoltaic power generation in strong sunshine The system first meets the power consumption of AC load, and then sends the excess power to the power grid; When the sunlight is insufficient and the solar cell array cannot provide enough power for the load, it can be obtained from the power grid or battery pack to supply power to the load. Of course, if the cost is taken into account, the battery can not be connected. When the light is insufficient, it can directly ask the power grid for power supply for the load. Compared with independent system, grid connected AC power generation system eliminates energy storage equipment.     There is also a grid connected extended hybrid power generation system. Hybrid type is between grid connected type and independent type. This system is usually integrated with the controller and inverter. The computer chip can be used to control the whole system to achieve the best working state. Figure 32 shows the hybrid photovoltaic power generation system. The difference between it and the above two systems is that there is an additional standby generator set. When the photovoltaic array power generation is insufficient or the storage battery is insufficient, the standby generator set can be started. It can not only directly supply power to the AC load, but also charge the battery through the rectifier. Hybrid photovoltaic power generation system is mainly used for the combination of electric fields far away from the power grid and ensuring the continuity of power supply, such as field hospitals, scientific investigation stations, etc. Once there is insufficient light or rainy weather, the solar cell cannot work, and the power stored by the battery cannot meet the needs, the generator set will replace the solar cell to supply power to the system. Different levels of photovoltaic grid connected voltages are different. For example, grid connected photovoltaic power stations above MWP level generally need to be connected to public power grid above 10kV, and other designs are roughly the same. The photovoltaic module converts solar energy into DC electric energy under the photovoltaic effect,can be used for solar street lights Then it flows into the grid connected inverter through the lightning protection distribution cabinet, which reverses it into AC meeting the power quality requirements of the power grid, and is connected to the 380V / 150Hz three-phase AC station power system for grid connected power generation. During the day, photovoltaic power generation will supply power to the power load of the station and feed the excess power into the power grid; When the power generation is insufficient in the evening or rainy days, the public power grid will supply power to the station power load. The photovoltaic grid connected power generation system is equipped with a set of local monitoring device with Ethernet communication interface, and the working state and operation data of the system are provided to the integrated automation system of unattended station through the interface to realize remote centralized control station monitoring.
