  • Page 28: Figure 8: Rms Value Calculation (Example, Not To Scale)

    The arithmetic mean value for phase current and voltage is generated on the basis of the RMS values. You can set the time interval 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 interval (WAGO-I/O-CHECK or parameters 37, 38, 39).

  • Page 29: Figure 9: Allocation Of Active And Reactive Energy In The 4 Quadrants

    ‘Rogowski’ coils are reversed! Active power minimum and maximum values are determined over a configurable time interval (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.
  • Page 30 The representation of the energy values can be scaled using a defined factor in the process image (PI). This factor can be set by the user with WAGO-I/O-CHECK or register 35 and can be changed at any time. The two examples below illustrate the...
  • Page 31 WAGO-I/O-SYSTEM 750 Function Description 750-495 3-Phase Power Measurement Module Harmonics analysis The I/O module calculates the frequency spectrum for the periodic input signals and analyzes the fundamental component and the next 40 harmonics for each phase. This analysis can be conducted on one of the three phases (L1 or L2 or L3).

  • Page 32: Figure 10: 4-Quadrant Display For Active And Reactive Power

    The 4-quadrant display appears as follows: Figure 10: 4-quadrant display for active and reactive power The 4-quadrant display is also shown in WAGO- I/O-CHECK for the measured value views "Overview", "Phase Lx" and "Power" in the dialog "3-phase power measurement".

  • Page 33: Measuring Errors And Accuracy

    The result is the fault current (t) - i SUM Lx If it is higher than the set threshold (WAGO-I/O-CHECK or Parameter 32/33), signaling is carried out in the process image (PI). Type of current transformer!
