eXpertMeter™ nasce dalla combinazione di quattro dispositivi elettronici intelligenti (IED): un powermeter multifunzione, un contatore di energia elettrica di elevata precisione, un analizzatore di Power Quality ed un Registratore di Transitori.
Le funzioni di Power Quality sono conformi alla norma CEI-EN-50160. La batteria ricaricabile di back-up consente un logging accurato di interruzioni e buchi di tensione, quale prestazione unica di eXpertmeter.
Le misure di Power Quality sono conformi alla norma CEI-EN-61000-4-30 Classe A.
eXpertmeter è un contatore elettronico di energia elettrica con funzioni di Power Quality di ultima generazione.

The eXpertMeter™ has been developed to comply with the most demanding customer requirements in energy generation and distribution (power stations, electrical companies, substation operators, electrical energy system integrators) and in energy consumer segments (industrial and commercial). The eXpertMeter™ can serve as a main revenue meter or test meter to manage advanced energy supply contracts that include a commitment to the most demanding power quality standards. The eXpertMeter™ can be used to resolve disputes between electric energy suppliers and consumers regarding power quality standard violations.
This device provides the most advanced communication capabilities, such as built-in infra-red port, serial communication (RS-232/RS-485), Ethernet and USB. With its hot swapping field replaceable modules, the eXpertMeter™ can be tailored to specific needs by adding additional communication capabilities, I/O capabilities or auxiliary power supply.
