Electric Meters
Hello friends,

Traditional electric meters display turning dials or spinning discs which measure kilowatt-hours, or KWh, and are interpreted by reading each dial or disc separately, with each representing units of Watts in thousands, hundreds, tens and ones. New electrical meters simply present the total kilowatt-hours used by the customer on a digital display, not unlike an odometer shows distance travelled by a vehicle. Each numerical increase represents another kilowatt-hour used and electrical consumption can be monitored by subtracting a previous reading from a new reading to give the number of units used within a certain period.

RE: Electric Meters
Hello Members,

An electricity meter or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device. Electricity meters are typically calibrated in billing units, the most common one being the kilowatt hour. Periodic readings of electric meters establishes billing cycles and energy used during a cycle. In settings when energy savings during certain periods are desired, meters may measure demand, the maximum use of power in some interval. Time of day metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Also, in some areas meters have relays for demand response shedding of loads during peak load periods.
