Electricity Usage Display Devices
The electricity usage display devices are the add on equipments which provide consumers with the approximate information on the amount of electricity being used by them. It is important to note down that these display devices for electricity usage are not the replacement of traditional electric meters installed at user’s home to measure the consumption of electric power. However, these electricity usage display devices are of great help to customers as they can keep track of their electricity usage and also control the same if they want to.
The display devices for electricity usage are used for displaying power consumption rates comprises of a register meant for storing and then displaying the cost of a unit of power, e.g., the cost per kilowatt hour as assessed by the local power company. The display panel shows the cost of power consumed over a certain period of time such as an hour taking into account the then existing instantaneous rate of power use. There is another section in the display panel of the display devices for electricity usage which indicates the rate of electricity projected to be used over a coming period of time such as a day, assuming that the then-existing instantaneous rate of power usage is maintained. The panel also indicates the cost of power projected to be consumed over a third time period such as 30 days while fourth, fifth and sixth displays provide the instantaneous rate at which power is being consumed as well as totalized actual costs over two different time periods. A register is designed in such away that it carries out all the adjustment whereby the cost stored in the register of a unit of power may be changed. The information displayed by the device may thereby be kept current and accurate even though electrical rates may change. The front panel of the device is human engineered for easy readability and first presentation of the most important information.
These display devices for electricity usage are really very helpful for consumers; however there are smart meters coming up which will be having all the combined features of traditional electric meters and these electricity usage display devices. Then there would be no need to install two different devices for measuring and tracking the electivity usage.
