Things to Consider Before Buying an Electric Meter

There are numerous types of meters which can be utilized for monitoring and showing the number of units consumed. Some intelligent meters are also capable of power monitoring, transformer monitoring, and load management as well. The smart meter is giving access to the real time consumption of power and saving money and time along with reduction of power usage by suggesting changes in behavior patterns. The modern metering system is also having touch screen and has two-way communication with automated controllers and are very easy to understand and analyze. The following are some important factors to consider before opting for an electric meter.

Phase Connection (Single or Three Phase)

First thing to consider before selecting an electric meter is to know of the phase requirement. Most of the electric power companies are offering single phase meters to their consumers, however a few also offer 3-phase meters as well. The single-phase meter is used in the applications when the alternating current power where electric charge is reversing its direction periodically. The three-phase meter is used where the alternating current power is to be used through three of more conductors having the charge to reverse direction alternatively in a periodic manner. The voltages are having an offset of one-third of total period of the wave or period. The meters are in 2 and 4 loops where these supports a vast number of different input types e.g. kVARh, kVAR, kVAh, kVA, kWh, kW, Irms, and Vrms etc.

Number of Amperes

After you know the phase requirement, now you have to look for the number of amperes you would need for your house or building. There are certain power meters which can bear up to 1000 amperes with the help of a clip-on transformer. The ampere support is different for different types of transformers. The latest intelligent transformers are having an accuracy of unity power factor asymptote as well.

Protocols for Communication

The protocol information is not necessary if you will opt for a traditional meter. However, if you want to have a smart electric meter then you must know of its communication protocols. The smart meters are communicating through different protocols and mediums for exchange of information with consumers as well as electricity providing company. For example, Modbus is one of the most commonly used protocols for the application of industries. Some of other protocols are TCP, PLC, and data acquisition protocols etc. The right meter with right communication protocols will enable you to setup a system quickly and make it in running position withing couple of hours.

Other Factors

After the selection of phase, protocols for communication and ampere number, there are some other important aspects to look for as well in a meter. You have to look for other features as well such as HMI software and SCADA for the automation of the entire electrical setup. SCADA can be very useful, especially when looking for the status of entire equipment, sending and receiving messages and emails, accessing data logs, and having a control on the reports being generated. Touch Screen is also an important feature to look for in modern electric meter and anywhere Electrical Meter Moves.
