Neptune ducati offers the sim from the italian sistema integrato di misura [integrated measuring system]. It has been developed for use in distribution networks of electric energy at low voltage, both single-phase and three-phase unbalanced, symmetric and asymmetric in addition to dc networks. The sim analyzer obtains measurements, which include the frequency, the voltage between phase and neutral, the phase current and it calculates, with extreme precision, the power factor, the power, the energies, the current of the neutral, the spectral components of voltage and current up to the fiftieth harmonic and detects voltage interruptions. The acquired and calculated values can be saved on the memory card; printed in numerical form or as a histogram and transmitted to a pc via serial port. The sim is characterized by a clear interface, which is simple to use and which makes it possible to quickly and easily obtain the result of the analysis.
