1.2 Problem Statement
Based on observation, consumers have been introduce d with ‘energy saving
device ’. However, the effectiveness of energy saving device ESD comes with several
problems to the consumer. The problem summarized as follow:
1. Consumer does not know how the ESD operates and how it can reduce
electricity. 2.
Consumer do not exposed with the safety precaution while using the ESD. 3.
Consumer argue about the amount of electricity consumption save after install the ESD.
4. Either true or not that the ESD can stand on different type of loads.
1.3 Objectives
Specifically this study embarks the following objectives:
1. To study the components and the operations of the ESD.
2. To investigate the effectiveness of ESD when operate on different power
usages. 3.
To investigate either there are reduction in the cost of electricity after the installation of the ESD.
1.4 Scope
This study focused on the how effectiveness of energy saving device ESD and how it affected the power consumption of electric system. In order to achieve it, the scope
is investigating characteristic of ESD that has been used. The chosen ESD in the Malaysia’s markets has been bought and used in this study.
3 Afterwards, ESD was installed in a house with single phase house power supply.
The installation was done in a house in Melaka. Then, the data were collected through power consumption of daily electrical appliances usage. The value of voltages, currents,
real powers and power factors of electrical appliances in the house has recorded by the digital wattmeter and fluke digital multimeter. The data were collected in a week for before
and after the installation of the ESD. This study only limited to the effectiveness of the ESD.
1.5 Report Outlines
Chapter one provides background of study, problem statements, objectives, scope, and report outlines. In chapter two, the literature reviews of the components and operations
for energy saving device ESD, the effectiveness of ESD, power factor correction and power consumption of electrical appliances are presented. The literature reviews is
provided to support the methodology and discussion. The literature reviews have been found by using the journals and direct survey to the industry. Chapter three is all about
methodology. It provides the method to study the components and the operations of the ESD, to investigate the effectiveness of ESD when operate on different power usages and
how to investigate either there are reduction in the cost of electricity after the installation of the ESD. Chapter four presents the results obtain from the data collection and calculation
of power factor and how it can be improved. Chapter five provides the conclusion and recommendation about the power consumption. Figure 1.1 shows the report outline of the
study.
