Abstract:
The aim of this study is to analyse the framework of an equipment
created to inform the amount of electricity used by customer to
National Electricity Company (PLN) through telephone line. The
method used in the research is a method which design a circuit of
logic to tone converter to be decimal numbers through telephone
network. The result of the study shows that using this equipment may
replace the manual record carried out by PLN personnel. The amount
of electricity utilized by customer is recorded by the equipment and is
sent through telephone line. This research also shows that data
produced by logic to tone converter are transmitted at the same time
as clock pulse to shift register. As a result, data received by shift
register may not be accurate. To overcome this problem, several delay
times to impede clock pulse are needed. This study demonstrate that
the design of the telephone line KWH reader equipment worked
consistent with the framework
