- An electric meter or
energy meter is a device that measures the amount of electrical energy
supplied to or produced by a residence, business or machine.
- The most common type is
more properly known as a kilowatt hour meter or a joule meter.
- When used in
electricity retailing, the Utilities record the values measured by these
meters to generate an invoice for the electricity. They may also record
other variables including the time when the electricity was used.
- The meters fall into
two basic categories, electromechanical and electronic.
- A Smart meter generally
refers to a type of advanced meter (usually an electrical meter) that
identifies consumption in more detail than a conventional meter; and
optionally, but generally, communicates that information via some
network back to the local utility for monitoring and billing purposes
(telemetering).
- The term "Smart meter"
typically refers to an electrical meter, but the term is also starting
to be applied to the measurement of natural gas and water
consumption.
- Analog part of the
solid-state energy meter consists of following blocks: two sigma-delta
modulators, bandgap voltage reference, two buffer circuits, and analog
multiplexer.
- Large commercial and
industrial premises may use electronic meters which record power usage
in blocks of half an hour or less. This is because most electricity
grids have demand surges throughout the day, and the power company may
wish to give incentives to large customers to reduce demand at these
times.
- The electronic power
meters are preferred both by the consumers and the energy enterprises
because they offer significant advantages in the accounting process as
accurate readouts, flexible schemes for tariffs, for payment and other
possibilities.
- Energy meters
(e-meters) are used worldwide to account for individual usage of
electricity at the location of delivery.
- Historically these
meters have been electromechanical in nature, and periodic on-site
reading of the meters was necessary to collect usage information for
customer billing.
- The latest generation
of meters is electronic and provides new features including networked
communications, self-test, and intelligent accounting for various time
periods.
- The electronic metering
raises demands for new technologies to be developed to utilize more
deeply the information generated in the accounting process.
- The technology under
development is attempting to combine the modern tendencies in the
information processing with the practical and standard means for
realization.
- Digital energy
measurement technoogy is being used in millions of chinese energy meters
todays. Some chinese meter manufacturers are eyeing the export
market.
