UPS AND ENERGY CONSERVATION JK LAKSHMI CEMENT LTD. JHAJJAR,HARYANA

3. An Uninterruptible Power Supply / Source,
UPS & battery backup, is an electrical
apparatus that provides emergency power
to a load when the input power supply fails.

4. PARTS OF UPS
UPS SYSTEM contains the following parts :-
• CHARGER CARD
• BATTERY
• INVERTER CARD
• DISPLAY CARD
• EMI FILTER
• STABLIZER
• BUZZER
• FAN

5. .
CHARGER CARD:- It consists of a rectifier which
converts AC in to DC to charge the Battery.
Input Output
Main AC supply DC
It converts the DC into AC.INVERTER CARD:-
ACDC

6. EMI Filter:-
An EMI (Electromagnetic Interference) filter helps to
reduce spikes and electrical noise.
INVERTER EMI Filter
AC
with
Noise
&
spikes
Pure
AC
STABLIZER:- Regulates the voltage to the constant range that
is safe for the loads.
DISPLAY CARD & BUZZER :-
•LEDs are used to indicate the user about the UPS status.
Status :- overloading, charging ,online/ offline.
•BUZZER is used to give warnings like:
 Low battery
Overloading
FAN:
-
It is used for the cooling of UPS System.

13. The mains to battery changeover time or battery
to mains changeover time is very low as
compared to inverter.
Changeover time in inverter is 500 msec.
Offline UPS has changeover time of 3-8 msec.

14. Offline UPS are normal weight UPS and are widely used for domestic Purpose.

15. On line UPS always remains on battery, whether input
supply (AC) is present or not.
When mains supply (AC) is present, it provides power to
DC supply of inverter section & charges the battery bank
conjointly.
When mains supply (AC) is not present, it will run the connected
load to the battery bank.

17. The battery to power converter / inverter is
always connected to the o/p of the UPS.
When the input supply (AC) fails, transfer
switch opens and then the inverter starts
functioning to load immediately.

19. APPLICATIONS:-
UPS generally used , where data loss causes
a serious problem like in:-
• Computers
• Operation Theaters
• Banks
• Control Room applications

20. DIFFERENCE B/W UPS & INVERTER
UPS
• It has high switching speed
& very low switchover
time(2 to 4 ms).
• It is used for computer
applications.
• Output is sine wave.
INVERTER
• It has low switching speed
& high switch over time (20
to 40 ms)
• It is used for home
appliances like TV , Fan ,
Tube-light etc.
• Output is square wave.

23. RENEWABLE ENERGY:
Renewable energy
can be generated
continuously
practically without
decay of source
Solar energy ,
Wind energy ,
Geothermal
energy , Hydro
energy

25.  Energy lights our cities, powers our vehicles, and
runs machinery in factories. It warms and cools our
homes, cooks our food, plays our music, and gives
us pictures on television.
 Energy is defined as the ability or the capacity to
do work.

27. We have limited resources available on earth.
 Our demands are continuously increasing day by
day.
 It is possible that someday most of the non-
renewable resources will be exhausted and we will
have to switch over to alternate energy

28. Limited Fuels
• At present consumption levels-
• Crude oil will last only for 40
years.
• Gas will last for 60 years.
• Coal will be finished in nearly
200 years.
• Ever thought of life without oil
and gas?

29. We save our money
when we save energy.
We reduce pollution
when we save energy.
We save our energy
when we save energy.

30.  RECYCLE - compositing waste materials into
new products to prevent waste of potentially useful
materials.
 Turn off all electronic devices that are not in use.
Not only turn them off but try to remember to
unplug them. You will be surprised how much you
will save with this simple step!
 Replace old light bulbs with energy saving
fluorescent bulbs. They may cost more, but will save
you much more in the long run.

32. At Home
•We should not keep lights
unnecessarily switched on.
• Reduce the energy your
appliances consume by analyzing
star ratings.
• Improve your water heating
efficiency to reduce energy costs.
At Public
Places
• Switch of the fans and lights in the
places like bus terminal and railway
stations when not necessary.
• Switch off the street lights.
• Big Hoardings, lightened up for the
whole evening and nights are other
wastage of power which can be and
should be avoided

33.  Let’s Take an simple example
• Power saved: 100W-13W = 87W
=87W X 6 Hours X 365 Days
=17520 WH
=17.520 kWH or Units
=Rs. 52.56
Say Rupees 50 per one bulb replaced.
We replace one 100W bulb with a 13W CFL and assume electricity is available for Rs.
3.00 per unit. and this bulb is used for 6 Hours a day.

34.  About 70% of India's energy generation capacity is from fossil
fuels, with coal accounting for 40% of India's total energy
consumption followed by crude oil and natural gas at 24% and
6% respectively. India is largely dependent on fossil fuel
imports to meet its energy demands.
 By 2030, India's dependence on energy imports is expected
to exceed 53% of the country's total energy consumption. In
2009-10, the country imported 159.26 million tonnes of crude
oil which amount to 80% of its domestic crude oil consumption
and 31% of the country's total imports are oil imports. The
growth of electricity generation in India has been hindered by
domestic coal shortages[ and as a consequence, India's coal
imports for electricity generation increased by 18% in 2010
