Abstract
In the modem industrialized society, where power
is essential ingredient of economic development.
It is not being wasted unnecessarily. One of them
is the street lights on the poles which remain ON
even in the day time and a severe amount of
power is wasted. One of its reasons is the
change of season i.e. the timing of switching ON
and OFF In winters and summers is not the same.
If operated manually sometimes they are not
turned ON even in the dark or they remain ON late
in the morning, when it’s not required.
If they would be switched properly,
not only It will help in the saving of power and save
money but the peoples travelling on the roads gets
facilitated However, in this era of changing
technology, street lights are also being
operated by GSM technology, which adds cost
due to the bulky hardware and software used and
yearly maintenance expenditure for the system also
GSM unit is fitted at the bottom of the pole
making it much prone to theft.
Features of Street Light Controller
 Specially Designed for Street Light Automation project.
 Pre programmed Time switch as per season specially Designed for Street Light
Automation
 Three Programs every month and for twelve months thirty six programs.
 No need of reprogramming & rewiring.
 User-friendly, low running cost.
 Energy saving Efficient.
 Capable in Lowered Co2 Emissions.
 Capable of Saving Energy 35-40%.(Depend upon user usage)

9. SUBTECHACCL cum Current Limiting Device
The Changeover doesn’t have any
current limitation and consumers sometimes exceeds the
load, so just to prevent it, so MCB’s are used to limit the
current but this is also not safe & comfortable as once the
MCB is tripped due to overloading, it doesn’t auto-reset, we
need to ON it manually. This procedure repeats itself &
become a headache to us. One more thing is high rating
MCB only trip at whenever it exceeds its allotted current.
But now this headache transfer to the generator and it is
overloaded. This overloading creates problems and also
decrease the life of generator. Whereas unlike high rating
MCB, CLD have it’s internal tripping system.

14. Automatic Power Factor Correction (APFC) Panel
In present era power network is go through a wide variety of
electrical load which create a varying power demand in the power
supply system. So in this varying condition of electrical load it’s very
difficult to maintain a constant power factor by the use of fixed
capacitors bank to be manually switched on/off to suit the variation of
Electrical load. As far as industrial load concern heavy inductive load is
very common which will results in Low power factor. Low power
factor results in higher demand charges and also of low power factor
penalties.
It is therefore necessary to automatic
switching operation of the suitable capacitor bank for fixing power
factor from load fluctuation. This can be achieved by Automatic
Power Factor Correction Panel.
