DESIGN AND DEVELOPMENT OF 3 PHASE POWER METER

In recent years, research into energy saving has been increasing in view of dealing
with environmental problems and effectively using energy resources. Hence,
embedded applications for energy saving and monitoring in industrial environment
has gone up steadily. However, most applications are limited to measurement of
power consumption ofthe whole facility rather than individual devices. Therefore, a
3 phase power meter has been designed specifically to measure power consumption
on a single device. Different from the conventional power meters, this meter is
designed to be plugged-in directly into the power supply socket meanwhile the load
will be plugged-in onto the power meter socket. This idea will remove the need of
wires that conventionally used and suitable for temporary or permanent installation.
The project focused on using Programmable interface controller and linear isolated
analog sensors to achieve safe power measurement procedure. The measurement
result is expected to be accurate and acceptable.
