Q&A
Q: What are the differences between smart energy meter and ordinary
energy meter?
A: 1) Ordinary energy meter only has the energy metering function.
While besides the basic function of energy metering, smart energy
meter also has other various functions, such as data storage, real
time monitoring, automatic control, information exchange, etc.
Besides, it is provided with multiple functions, such as forward
and reverse measurement, TOU measurement, remote meter reading,
remote monitoring and control, electrical parameters measurement,
security protection of consumed energy information, event logs,
etc.
2) Compared with previous energy meters, smart energy meter is
added many new functions, such as measurement information
management, information management of energy consumed, monitoring
of energy quantities consumed, etc., which can better provide users
with accurate and timely billing function.
3) It has the bidirectional metering function and supports the
distributed energy utilization. In addition to recording the import
energy, it also can record the export energy. If the user is
self-built with distributed clean energy generation facilities,
such as wind energy, solar energy, etc., it can realize to transmit
the spare energy to power grid when the generated power cannot be
exhausted, thus achieve energy conservation and environmental
protection to reduce carbon dioxide emissions, create low carbon
life and improve the users' economic benefits.
