• EMA meters the energy values in 4 quadrants. It can monitor the energy consumption, the energy produced and the difference between the energy produced and consumed, in cogeneration or photovoltaic systems for instance.
• EMA keeps an account of the energy consumption according to timebands that can be selected by the user, allowing him to double-check with the bill at the end of the month.
• EMA reads and displays the energy values measured in other energy meters connected to the network. This is achieved thanks to digital inputs, which are able to acquire the impulses generated by the meters in the installation. In this case, EMA acts as a data concentrator. It not only collects information from the electricity meters but also from the water and gas meters, after which all the data can be transmitted to the remote monitoring system.
• Moreover, EMA allows a complete, in-depth analysis of the quality of the network to be made thanks to measurement of the harmonic distortion rate of the voltage and current signals measured through to the 31st harmonic. Display of the wave form for both voltage and current allows signal deviations from the ideal situation to be observed in real time, without interference, and highlights any signal interference.
