Cross-phase three-wire three-phase reactive energy to do sub-element analysis of the problem when verifying
Angle. Standard table indicates: Q = in60. = 130var; Q = sin0. = 0: Q = Qo + Q,[link widoczny dla zalogowanych], = 130var. Measured cross-phase reactive reactive form acceptable to: V ・ cos (-60.) + West cos (a 60 ~) = 150var. Taking into account the measured cross-phase reactive power meter calibration system (1) All e-check station with the general phase shift method of any reactive energy meter calibration is not unexpected, because the standard form of the phase shift method also uses the principle . On 3-phase 4-wire cross-phase reactive energy meter calibration, no problem. (2) All e-check with the general 3-phase 3-wire sets of cross-phase combined reactive energy as per check, no problem; but when they do point per verification significant error, and the error due to phase and different, because the power angle to another. This is not a problem of the table was seized, but the problem with the check station, exactly is the standard form used mistakes. (3) again: only reactive with the cross-phase cross-phase calibration standard table for reactive energy. In fact, the standard form of modern multi-functional design, it is not difficult, but the lack of industry experience in product design flaws caused. (4) The phenomenon of professional and technical personnel for energy metering should be able to understand. Only in recent years widespread use of electronic units and electronic units to improve performance, the use of electronic units of the young technicians are superstitious intelligence units,[link widoczny dla zalogowanych], while the table appears under certain conditions the \This article is intended only to \Reference [11 Xiao Yongqing, Guo Zikun, Lei Huibo.

Using this program,[link widoczny dla zalogowanych], together with the corresponding hardware design, may constitute a common network access system, a non-network devices connected to the Internet to provide a good solution.
