  In a power distribution system of most of the buildings, A Low Voltage (L.V.)
switchboard was applied to protect the system. There are different components
in the switchboard (e.g. circuit breakers, over current protection relay, earth
fault protection relay etc.). There are also some components for measure the
power quality which is the power analyser. A power analyser (including
Voltmeter, Ammeter, Multi-meter) is using to measure the power quality in the
electrical power distribution system. Most of the electrical power
distributions systems have been connected the power analysers to a building
management system. The power analysers connected to a computer in a fixed
position that means if someone wants to check the power distribution status,
the person needs to go to the computer to check. In this project, a system
would be made to monitoring the power status by 5G New Radio (NR) Network
application with android smartphone. Since 5G NR Network can provide a
theoretical peak download capacity of 20 Gigabits per second. It would be more
convenient to monitoring the power status in different place by checking though
in the Internet of Things (IoT)
