Abstract
The reading of an electrical kilowatt hour (KWH) meter, for domestic consumers, is done manually by employing many people to record the reading from house to house. This is obviously inefficient. In Malaysia the number of electricity consumers increased by 4.9% every year. This results in having more manpower to read the meter manually. The objective of this research is to design a KWH meter reading system using telemetry. This will reduce the employment of human resources for meter reading. The meter reading become more accurate and efficient. The whole process of recording the KWH meter can be done in one control room. The KWH meter reading system can be divided into two parts. The first part of the system is a direct measurement until. It consists of a modified conventional KWH meter to read the data in digital (i.e binary code). This binary code is then converted into DTMF signal so that it can be send through telephone line. The second part is the remote meter reading system. It consists of a DTMF demodulator which converts the DTMF signal into a binary number and displays the number in decimal form using 7 segments displays. Every units of the telemetry KWH meter reading system has been tested in order to check whether the system is working or not. From the testing, a consistence and accurate system has been successfully developed.
