INTRODUCTION
 Impact College of Engineering and Applied Sciences (ICEAS)
was started in the year 2004 and campus having an area of
about acres is one of the finest sites in Bangalore. Today, the
Institute is recognized as one of the center of academic
excellence in the country. Over the years, there has been
significant process at ICEAS in all academic, and a parallel
improvement in facilities and infrastructure, to keep it on per with
the best institutions in the country. This institute is affiliated to
Visveshwaraiah Technological University. It has an intake of 360
students sanctioned by Government of Karnataka and approved
by AICTE; Students from various parts of country have taken
admissions.

Time of Day Increase(+) /Reduction(-) in energy charges
over the normal tariff applicable
22.00 Hrs. to 06.00 Hrs. (-)125 paisa per unit
06.00 Hrs. to 18.00 Hrs. 0
18.00 Hrs. to 22.00 Hrs. +100 paisa per unit

Benefits of Monitoring Power Quality
 Ensure optimum system performance and
efficiency. Reduce total system loading.
 Improve availability of power
 Minimize losses to the production processes.
Increase plant productivity.

4. z
LITERATURE SURVEY
 First we took the electricity bill of our college and
we found out that kWh and kVA consumption are
varying. We are paying penalty during most of the
months due to crossing the limit of contract
demand. For this we referred reports on energy
conservation AIT College and from various
electrical related articles and magazines (Electrical
India and Lighting India)

5. z
Need to Conserve Energy Instead of
Generation
 We use the energy faster than it is produced
i.e., there is a rapid increase in electrical
equipment’s used by consumers than it is
generated.
 The basic necessities like coal, oil, natural
gas the most utilized sources take thousands
of years for information.
 Most of the resources are limited.

6. z
ENERGY AUDIT
 The purpose of an energy audit (sometimes
called an “energy assessment” or “energy
study”) is to determine where, when, why and
how energy is used in a facility, and to identify
opportunities to improve efficiency.

7. z
Energy Audit Methodology
 Survey of the facility and collection of data.
 The pre-planning walk through the plant to
identify energy saving components for
familiarizing the energy.
 Data Analysis.

8. z
Energy Audit Covers
 Operational efficiency of diesel generator
sets.
 electric supply authority.
 Evaluation of different components of the
electrical network
 Study of utility equipment like fans, pumps,
air-conditioning and lightning, etc.

9. z
FUTURE WORK
 Implementation of all suggestions mentioned in
lighting, air-conditioning, computers etc.
 Installation of energy meters in all blocks taking
readings. Resizing of cables, switch gears.
 Setting of time-table i.e. ,labs which helps in
equal distribution of load

10. z
Objective of Project Highlighting
 To know and understand the level of power factor and
harmonics present in electric
 Network of Impact College of engineering and take
necessary steps to improve the power quality.
 Perform a literature survey to determine if any work has
to been previously done in this field.

11. z
POWER QUALITY
 Equipment designer or manufacturer: a
perfect sinusoidal wave, with no
variations in the voltage, and no noise
present on the grounding system

12. z
POWER QUALITY CAN IMPROVED BY
 Power factor correction. Harmonic filtering.
 Special line notch filtering.
 Transient voltage surge suppression. Proper
earthling systems.

13. z
SMPS
 A switched mode power supply (SMPS or
Switcher) is an electronic power supply that
incorporates a switching regulator to convert
electrical power efficiently. Like other power
supplies, an SMPS transfers power from a
source

14. z
OVER ALL SUGGESTION
 Lightening system
 Room Air Conditioners
 computers

15. z
RESULTS
 Collection of all the bills form the
particular year .
 Collection of Load Data:
 Harmonic Analysis

16. z
CONCLUSIONS
 The power quality problem is now of a great concern
to electric utilities of power industry and they are
trying hard to supply their customers with a good
quality of power especially in the power market.
 Installing filters at feeding points along the network
can do this if the harmonic components magnitudes
as well as their phase angles are known in advance.
