Dear Friends / Sirs,
Below Figures shows the effect of variation of voltage on light output and power consumption and life.
Similar variations are observed on other gas discharge lamps like mercury vapour lamps, metal halide lamps and sodium vapour lamps.

Reduction in lighting feeder voltage can save energy, provided the drop in light output is acceptable.
If rated voltage for light used is 240 Volts than keep voltage at 96-97% i.e. 230-233 Volts (Ph-N) Approx i.e. 400 -405 Volts (Ph-Ph).
In Many areas, night time Grid voltages are higher than normal; hence reduction in voltage can save lot of energy and also provide the rated output (As Majority of lights are on during night only).
Hope this may be helpful in your plants.
And yes your suggestions are welcome

4 年Many plants are in process of changing over from HPSV to LED lighting. In view of this we have already installed 380V output lighting transformer achieving energy savings & optimally light output ( lux level).

4 年Mr Avinash I too would like to have the PDF for this article. Thank you
Head Electrical Department
4 年Sir Is there any impact, in power saving if we used LED

4 年Avinash, Would it be possible to share these with me via pdf. Email? I would like to share them with my crew to read during this trying time. John
