Street lighting design calculation.

The height of pole is 26 5 foot. Street illumination level in lux e al x cu x mf w. Calculate voltage drop of cable for street lighting poles voltage is 230 400 v 3ph power factor is 0 85 allowable voltage drop up to 3 max. Street lighting is to be designed using the illuminance method for calculations prepared with agi32 software.

For a 230 volts system a voltage drop of 5 is allowed although in extreme cases 15 voltage drop is sometimes tolerated. Street lighting design in lighttools 2 how street lighting calculations are performed slu assumes that street lamps are far away from the surface that they illuminate so their intensity distributions positions and orientations are the only required data to calculate the test metrics in addition to the rtable. The width of road is 11 5 foot. This voltage drop calculations is valid for street lighting landscape lighting and site lighting using table mv a m and r x method for single three phase.

Digital design files from agi32 are to be provided to the city along with line loss. This calculations based on high pressure sodium hps lamp type which is. Calculate distance between each streetlight pole having following details road details. Street lighting design is the design of street lighting such that people can safely continue their travels on the road.

Luminaire of each pole. 1 calculate distance between each street light pole. Typical calculation of road lighting. Also excel file attached.

Street lighting schemes never brings the same appearance of daylight but provide sufficient light for people to see important objects required for traversing the road. Luminaries are properly selected and mounted on a location most feasible and effective with minimum cost.
