Portable Three-Phase Energy Standard
PEWM-3C
-
The three-phase energy standard PEWM-3C is used for quick on-site tests of all types of electricity meters – for active, reactive or apparent energy, two-, three- or four-wire connection. Three voltages and three currents are measured at the same time. The current can be measured either via direct connection up to 10A (class 0.1), or with three current clamps (CC) to 120A, 150A or 1000A (class 0.2).

Three-Phase Converters
SIRIO 3PH 7 ALFA 3PHSAP
-
The three-phase converter is an electronic equipment able to vary the RMS value of a sinusoidal voltage by controlling no. 6 controlled, antiparallel-connected conducting diode pairs.Since the wave form is symmetrically split both into positive and negative halfwave, the output voltage average value is not affected and equal to zero. This means that three-phase loads can be fed without gene rating inside the mesh a circulating current with average value other than zero.Moreover, the three-phase converting is obtained with only one control circuit thus ensuring balance between the three linked voltages applied to the load.
