The advantages of controlled smart electric energy meter

Jun 13, 2017

The main advantage of controlled smart electric energy meter over electronic and mechanical meters is connectivity. The networked smart meter can remotely report power usage, implement power management, collect usage time data and prevent certain types of stealing.

Other industries with mission-critical functions, such as automobiles and industries, introduce a "functional safety" concept for diagnostic requirements, which is essentially the ability to check equipment to determine whether it is in use before, during use and after use.

The current controlled smart electric energy meter test, relying only on the internal components of the live meter remains in the calibration range to estimate the accuracy, but this method there is a risk. Field accuracy monitoring is important because the sensor is exposed to high current, voltage events, and harsh environments due to the accuracy of the sensor. Therefore, the diagnosis must include monitoring the entire meter, including the sensor and all electronic components.
