Multi functional network power meterThe measurable power parameters in the power grid include: Ua, Ub, Uc (phase voltage); Uab, Ubc, Uca (line voltage) Ia, Ib, Ic (current); Pa, Pb, Pc, Ps (active power per phase and total active power); Qa, Qb, Qc, Qs (reactive power per phase and total reactive power); PFa, PFb, PFc, PFs (each power factor and total power factor); Sa, Sb, Sc, Ss (apparent power per phase and total apparent power); FR (frequency) 26 electric quantities and four quadrant electric quantities, all measured electric quantity parameters are saved in the electric quantity information table inside the multifunctional network power instrument, and these data can be accessed and collected through the instrument's digital communication interface. However, for different models of multifunctional network power meters, their display content and methods may not be consistent.
