| Summary: | The Standard procedure of the Tenaga Nasional Berhad (TNB), after sending a one month
warning letter and receiving no action from a customer with an unpaid electricity bill, is to
take the fuse out from the breaker (or fuse) box. This procedure needs access to the breaker
box. The breaker box is sometimes located in unreachable locations such as, placed too high,
locked gate, or inside a locked box. The objective of this research is to develop a remote
disconnecting system for the single phase fuse energy meter. The system is also capable of
reconnecting the supply once payment has been settled. The module is designed to work
with different Identification (IDs) number under varying obstruction conditions. In a
preliminary study of wireless communication using GSM, most researchers focused on
controlling energy meter through SMS. The Bluetooth is another wireless method of
communication to control the device, but it transmission is limited to a short-range below 10
meters, and limitation up to eight devices communicate in a single network. Besides, Radio
Frequency (RF) is also used as wireless communication. The range of RF maximum is 100
meters in an open airline of sight configuration without any interface. The module is based
on Arduino Pro Mini, RF unit as wireless communication with a frequency of 433 MHz, and
Solid State Relay as a switching device. The design for hardware included transmitter device
and receiver device. The software design is based on C language. Arduino IDE is the editor
used to write the program code. From the result obtained, for open space and wall blocking,
the distance measure 12 meters and covered with box achieved 11 meters from the
transmitter device. The result of the study also shows that a rechargeable battery is needed to
make sure the system can operate in the case power trip from TNB. Nevertheless, the system
has the potential to reduce non-payment issues in the future. |
