    RMS values. You can set the time period during which the mean value is to be generated using WAGO-I/O-CHECK, or parameters 34, 35, 36. The RMS minimum and maximum values for current and voltage are also determined over a configurable time period (WAGO-I/O-CHECK or parameters 37, 38, 39).

  • Page 34: Figure 8: Allocation Of Active And Reactive Energy In The 4 Quadrants

    Active power minimum and maximum values are determined over a configurable time period (WAGO-I/O-CHECK or parameters 37, 38, 39). In real supply networks, not all electrical loads are purely ohmic. Phase shifting occurs between current and voltage. However, this does not affect the method for determining the RMS values for current voltage previously described.

This analysis can be conducted on one of the three phases (L1 or L2 or L3).
